Answer:
The crop has good yield because Compost has a good effect on root crops.
Explanation:
Compost has a great effect on the development of root crops such as onion, potato, garlic and ginger etc. Compost provide nutrients to these crops as well as soften the soil due to which they grow rapidly. It also improved ventilation, soil structure and soil texture which is very necessary for the crop. Due to ventilation, oxygen gas is available to the roots which increases growth and yield of these crops. Compost also retain water and nutrients so they are available to the roots. So those plots where compost is applied observed increase in yield as compared to other plots.
A scientist examines a cell using a microscope and notes that the cell has a large number of mitochondria and ribosomes. Within the cell are proteins that can contract. Which of the following is the most likely cell type?
Muscle cells can contract in response to stimuli. Moreover, muscle cells also have a large number of mitochondria and ribosomes for energy requirements and protein synthesis, respectively.
All muscle cells can contract by the interaction of myosin and actin proteins, which form myofibrils, the repeating molecular structure of sarcomeres (the sarcomeres are the functional and structural unit for contraction). The globular heads of myosin bind to actin filaments, forming cross-bridges that cause the muscle cells to contract and expand.Ribosomes are organelles required for protein synthesis. Muscle cells have a lot of proteins, especially actin and myosin myofibrillar proteins, which are responsible for muscle fiber structure.Mitochondria are the energetic centers of the cell. In consequence, thousands of mitochondria can be observed in cells with high energy requirements such as muscle cells, which release a large amount of energy quickly for movement.Mitochondria, using oxygen available within the cells and metabolize food biomolecules to generate ATP (the energy coin of the cells) that power up the cell.Learn more here:

B.matter from producers, such as the cutleaf daisy,
is immediately recycled by decomposers, such
as a bacterium.
C. matters from all organisms, such as the Bald
eagle, is dissipated at each level and none of it
is recycled.
D. matter from the Sun is recycled after many years
by consumers, such as a Bachman's sparrow.
Answer:
There is no food web attached to this question but it can be answered because matter flows uniformly through trophic levels in all food webs.
The correct answer is;
A. matter from consumers, such as the green lynx spider, is eventually recycled by decomposers, such as a fungus.
Explanation:
A food web is an interconnected series of food chain showing how organisms feed on one another to obtain energy. A food web always start with a unique set of autotrophic organisms i.e. capable of producing their own food called PRODUCERS. Producers such as the cutleaf daisy in this question create the organic matter via the process of photosynthesis, which gets transferred to organisms that feed on them called CONSUMERS e.g green lynx spider
Consumers are heterotrophic i.e rely on other organisms for source of energy. As they feed on other organisms and get fed on, the matter gets transferred until the last consumer dies. The dead matter in the dead organism gets decomposed by organisms called decomposers e.g fungi and it gets recycled back into the soil as nutrients for use by plants.
Therefore, dead matter from consumers, such as the green lynx spider, is eventually recycled by decomposers, such as a fungus.

Draw a cross section of a peach, and label the structures. What parts of the flower give rise to these structures
Answer:
exocarpo is synonymous with exocarp
endocarpo is synonymous with endocarp
mesocarpo is synonymous with mesocarp
semilla is synonymous with seed
Explanation:
In phase one, the plant's ovary begins to grow abruptly, this is where the embryo and endosperm affect their size, but if this ovarian growth is interrupted by an external factor, it determines the size of the future.
Then, the embryo and the endosperm could grow and undergo a process called sclerification, which is the hardening of the interior of the fruit, that is to say, the future formation of the seed or vulgarly called "pit". .
After this, the mesocarp, which is what is called the fleshy body or subglobose edible drupe, begins to grow.
The growth of the mesocarp is what gives the volume, weight and body to the fruit, so that after maturation it exceeds the strength of the branch and it falls from the tree.

what is adaptation give any four characters of aquatic plants
Explanation:
Animals have special features that help them to live in a particular place. Therefore this features is called adaptation.
1] Aquatic plants have leaves that float on the surface of water.
2] Thier leaves are rarely have stomata.
3] Thier leaves can perform all the work without xylem.
4] They are usually lack cuticle layer in order to avoid excessive dryness.
Answer:
The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is frequently saturated with water.
Four characters of aquatic plants are as given below:
1) most aquatic plants donot need culticles or have thin culticles as cuticles prevent loss of water.
2) aquatic plants keep their stomata always open for they do not need to retain water.
3) on each side of their leaves are a number of stomata.
4) aquatic plants have less rigid structure since water pressure supports them.

Human actions often break large areas if forest or grassland into small remnant parcels that support fewer individuals and ae far apart from one another. Predict how gene flow, genetic drift, and extinction risk would differ between the original and the remnant populations.
Answer:
Gene flow will be restricted
Gene drift will be higher than in larger populations
Extinction rate will be increased due to the reduction in genetic diversity
Explanation:
Gene flow is defined as the transference of genetic material among populations. In isolated populations, the gene low is null and thereby they have different allelic frequencies, while populations that share genetic material tend to have the same allelic frequencies.
Genetic drift is the change in the allelic frequencies in a population as a result of random sampling. In small populations such as those living in parcels, the genetic drift is higher than in larger populations.
Extinction is the continuous declination in the number of organisms of a particular group (for example, a population or a species), that inevitably leads to the disappearance of this group. In small populations, the likelihood of extinction will be higher than in larger populations, due to the lesser genetic variation and higher genetic drift.
If the gametes from a diploid individual only contain one of the two possible alleles, it is not difficult to determine the genotypes of the gametes from that individual. For the diploid genotypes indicated below, write all of the possible genotypes of the gametes. If more than one type of gamete is possible, separate them with a comma. Diploid Genotype Genotype of Gametes RR rr Rr
Answer:
Diploid Genotype - Genotype of Gametes
RR - R
rr - r
Rr - R, r
Explanation:
According to Gregor Mendel in his law of Segregation, he stated that the alleles of a gene gets separated into gametes during gamete formation (meiosis). This occurs in such a way that only one allele of the two possible alleles that make up the genotype of a diploid organism is found in the gamete.
Meiosis is a cell division that reduces the chromosomal number of the daughter cells. Hence, a diploid organism (2n) will undergo meiosis to produce haploid (n) daughter cells (gametes). An organism with a diploid genotype RR will produce gametes which have only genotype R. The same applies to organism with genotype rr. Only gametes with genotype, r, will be produced.
However, in a heterozygous genotype like Rr, the different alleles will separate into gametes in an equal proportion i.e. gametes with genotypes R and r will be produced in a ratio 1:1.

A large portion of cellular respiration happens in the mitochondria. For this reason, the mitochondria are known colloquially as
the "powerhouses of the cell." Which body organ could best be compared to the mitochondria? (1 point)
Answer:
im thinking its the lungs, not 100% sure but seems like the best answer.
Explanation:
the main function of the lungs is the process of gas exchange (respiration), and mitochondria is also responsible for respiration too.
The lungs could be best compared to the mitochondria because it breaks down nutrients and releases energy for the body.
The stomach is an organ of the digestive system located between the esophagus and the intestine. Several processes occur in the stomach that help digest food, that is, digest the components of food that are used as energy for the body.
On the other hand, mitochondria are eukaryotic cell organelles responsible for cellular respiration, that is, for supplying most of the energy necessary for cellular activity.
According to the above, the correct answer is C because it illustrates the organ that is most related to the function of the mitochondria because both are essential to get energy.

What term is used to describe a retrograde flow of urine from the urinary bladder into the ureters that is the cause of recurrent urinary tract infections (UTIs)?
Answer:
Vesicoureteral reflux (VUR)
Explanation:
Answer:
The condition is known as Vesicoureteral reflux (VUR)
Explanation:
Vesicoureteral reflux (VUR) is a pathological condition caused by Urinary Tract Infections (UTIs) where urine flows back from the bladder into one or both ureters, and sometimes back into the kidneys. The condition is commonly seen in young children under 2 years of age, and infants.
Most children with primary VUR were born with an abnormal ureter, which is mainly seen as a defective valve between the kidneys and the ureters that does not close well, hence resulting in refluxes. Secondary VUR develops due to some pathological conditions affecting the urinary tract, like blockage of the urethra, causing reflux of urine. Defective bladder nerves can also lead to VUR.
During the Paleocene-Eocene Thermal Maximum, when global surface temperatures spiked, we observe temperate forests ____________________, insect herbivory of temperature.
Answer:
The overview of the problem concerned is listed below.
Explanation:
Mostly during Paleocene Eocene Temperature Optimum, we consider temperate vegetation momentarily relocated towards the poles whenever global average surface temperature jumped, bug harvesting temporarily escalated, as well as coral reef crashed.The level of variations in climate or temperature was as sluggish as it is today, which suggests that such past occurrences are likely to overestimate the effects of rising temperatures nowadays.Increase occur in the insect's population due to increase occur in global surface temperature.
During the Paleocene-Eocene Thermal Maximum, when global surface temperatures increase, we observe temperate forests having more population of insects due to favourable temperature for the growth of insects.
The productivity and distribution of forests could be affected due to change occur in the temperature, precipitation and the amount of carbon dioxide in the air. As the temperature increases the population of insects also increases which leads to increase in biodiversity of forest so we can conclude that increase occur in the insect's population due to increase occur in global surface temperature.

"I can be single celled or multicelled. I can reproduce sexually or asexually. I can be heterotrophic or autotrophic. I am Eukaryotic. What am I?"
Answer:
The correct answer is a protist.
Explanation:
A eukaryotic organism, which cannot be categorized as an animal, plant, or fungus is known as protists. They are majorly unicellular, however, some of them are multicellular like algae. Some of the protists can attain energy for living by consuming other organisms, that is, they are heterotrophic. While some obtain energy from the surroundings via the process of photosynthesis, that is, they are also autotrophic.
The protists are mainly found in water, however, some of them also thrive in moist soil. These species can be seen anywhere on the Earth, where there is liquid, even within human beings. The reproduction is some of the protists takes place sexually, that is, with the help of gametes, while in some of the protists asexual reproduction also takes place, that is, by the process of binary fission.
