Explanation:

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.

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.

It should be noted that muscles only work to produce movement through pulling, muscles cannot push. Therefore, the statement is true.

Muscles allow people to move by pulling in the joints. Muscles are required to breathe, exercise and stay healthy.

There are three main form of muscles in the human body and they're:

• Skeletal muscles: The muscles give the body its shape as they help in holding the skeleton together.

• Smooth muscle: They're also called the involuntary muscle. They consist of fibers and are controlled by the nervous system. They help in maintaining blood pressure.

• Cardiac muscle: This is the muscle that's found in the heart. It helps in ensuring that the heart function well.

In conclusion, muscles only work to produce movement by pulling, they cannot push.

Explanation:

Archaea have no organelles while Eukaryas do, in other words Archaea have DNA that is not in a nucleus.

The organisms in the domain archaea different from those in the domain eukarya is Archaea have no nucleus.

Archaea is a space of single-celled living beings. Prokaryotes are these microorganisms because they do not have cell nuclei. Initially referred to as archaebacteria, archaea were categorized as bacteria.

By interacting with both bacteria and their hosts, Archaea contribute to the ecosystem's and vegetation's functioning in the harsh bog ecosystem by carrying out functions related to nutrient cycling, stress response, and phytohormone biosynthesis.

The following characteristics of Archaebacteria have been identified as common: the presence of ribosomal and tRNA characteristics; 2) the absence of peptidoglycan cell walls, which are frequently replaced by a coat that is mostly proteinaceous.

Answer:

when two organisms exchange information and reproduce

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.

Answer:

See the answer below

Explanation:

An open system is a type of thermodynamic system in which energy and matter are being exchanged between the system and the surrounding. It is like boiling soup in an open pot. The opening allows for the addition of materials (matters) into the soup and energy is exchanged through the heating. A good example is found in biological organisms. They consume matters and exchange energy with the environment by carrying out work.

A closed system is a type of system in which there is no exchange of matter between it and the environment. However, there is an exchange of energy. It is like boiling water in a closed pot. Nothing can be added into the pot due to the closure but energy can be transferred through the heating of the pot.

An isolated system allows for neither energy nor matter exchange with the surrounding. It is like a closed food warmer that allows for nothing to enter or leaves it.

Answer: Open systems are energy that can be transferred between the system and its surroundings. Close systems are systems that do not transferred to its surroundings. Isolated systems is a thermodynamic system which cannot exchange either energy or matter from outside its boundaries of the system.

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.

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.

Answer:

Independent variable - vitamin gro and exercise routine.

Dependent variable - growth of children or nieces.

Explanation:

There are two variables present in an experiment called dependent and independent variables.

Independent variables are those variables which can be controlled in an experiment and dependent variables are those variables which are measured in the experiment under the influence of the independent variable.

In the given experiment, the independent variable will be vitamin gro and exercise routine and the dependent variable is the growth of children or nieces because vitamin gro and exercise routine can be controlled and growth of children is dependent on vitamin gro and exercise routine.

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.
