Habitat fragmentation is
caused by...
A.
overpopulation.
B. moving a species of animal to a different habitat.
C, oil spill from a boat in the ocean.
D. pieces of a habitat being divided.

Answers

Habitat fragmentation is caused by moving a species of animal to a different habitat. Option B.

Fragmentation occurs when part of a habitat is destroyed leaving a small unconnected area. It can occur naturally as a result of fires or volcanic eruptions but is usually due to human activity. A simple example is building a road through a forest.

Habitat fragmentation is defined as the process by which large habitats are transformed into a series of small patches of smaller total area separated by a habitat matrix distinct from the original habitat. Forest fragmentation can be caused by natural causes, such as lava flows and other natural disasters, or by anthropogenic causes, such as the conversion of forests to agricultural land or the development of infrastructure in protected areas.

which option correctly describes the mode of inheritance for sickle cell anemia
recessive, X-linked dominant, X-linked recessive Or dominant

Answers

The mode of inheritance for sickle cell anemia is recessive.

Sickle cell anemia is a type of inherited genetic disorder where the blood cells are shaped as sickle or crescent-shaped instead of being oval flat disc-shaped cells. This peculiar structure of the abnormal red blood cells deems them unable to carry sufficient oxygen to the tissues and organs of the body.

To be affected by sickle cell anemia, an individual has to inherit one copy of the sickle cell gene from each parent, irrespective of gender. Thus, it can be also called a type of autosomal recessive disease. The disease is only expressed in the homozygous recessive condition.

D. Lavoisier applied the results of one experiment to explain a wide variety of

Answers

Lavoisier's conclusions were considered a law instead of a theory, because Lavoisier provided sufficient empirical evidence to support his claim

What is Lavoisier law ?

In his tests, Lavoisier tried to show that his theory according to which matter is never generated nor destroyed in chemical reactions was true.

The knowledge of finance, biology, chemistry, and economics that Antoine Lavoisier possessed was well known. He recognised oxygen and articulated the law of conservation of mass in 1778. He detected hydrogen, developed the metric system, and changed element nomenclature in 1783.

He rightly inferred that water wasn't an element but rather a combination of oxygen and combustible air, or hydrogen as it is today known. Lavoisier used the breakdown of water into oxygen and combustible air to prove his point.

Based on its anatomy, infer which animal requires more energy: an Earthworm or a Salamander? Justify your answer.

Answers

Based on its anatomy, the animal that requires more energy is the Salamander. This is because it has a more complex anatomy and physiological structure.

Why do living organisms require energy?

Living organisms require energy because they have to perform metabolic activities for proper and ideal survival of organisms. Such organisms use numerous strategies in order to accomplish the task.

An earthworm delivers energy from the environment more easily than compared to salamanders. This is because they extract food energy from decaying organic matter like plants and animals that have died.

On the other hand, Salamanders deliver energy by consuming small insects and other tiny living entities. It uses a mechanism more similar to human beings.

Therefore, the animal that requires more energy is the Salamander. This is because it has a more complex anatomy and physiological structure.

41) Which of the following processes happens
during meiosis I?
A) Homologous chromosomes of a pair are
separated from each other.
B) The chromosome number per cell is conserved.
C) Sister chromatids are separated.
D) Four daughter cells are formed.

Answers

In meiosis I, homologous chromosomes of a pair are separated from each other. Option A.

What is meiosis?

Meiosis is otherwise known as the division of sex cells or reductional division. It is a division in which diploid cells divide to produce haploid cells.

Meiosis occurs in 2 main stages:

Meiosis IMeiosis II

Meiosis I consists of prophase I, metaphase I, anaphase I, and telophase I. Meiosis II, on the other hand, consists of prophase II, metaphase II, anaphase II, and telophase II.

At the prophase I stage of meiosis I, chromatin materials thicken to form threads and homologous chromosomes pair up to form a tetrad. Non-sister chromatids then go ahead to exchange chromosomal segments in a process known as crossing over.

At metaphase I, paired homologous chromosomes line up at the center of the cell to form a metaphase plate. Spindle fibers engage each tetrad.

At anaphase I, homologous chromosomes of a pair are pulled apart by the shortening of the spindle fibers. Their journey to the poles is completed at telophase I. This effectively ends the journey of meiosis I before the cell proceeds to meiosis II.

In other words, the separation of homologous chromosomes of a pair happens during meiosis I.

What is a hypothesis and controlled variables?

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a claim of how it works a relationship between two or more variables.

The researcher hypothesizes to predict what is going on or what is expected to occur.

A hypothesis

• must be clear and comprehensive.

• must express the direct relationship between the involved variables.

• must be objective.

• must be testeable and falsifiable

Controlled variables are those that need to be kept constant during the experiment to avoid their effect on the results. These variables are the same in the control and all the experimental groups, so they can not influence the results.  

In the exposed example,

Question ⇒ how does the amount of water given to these plants each day affect how tall the plants grow?

1) Hypothesis ⇒ If the plant receives the same amount of water every day, it will grow taller than plants that receive different daily amounts of water.  

2) Controlled variables ⇒ soil pH, temperature, light exposure

3) Measurement tool ⇒ millimeter ruler

This tool is useful to measure the change in tall plants daily. Being millimetric helps the researcher get a more accurate measure of the plant changes in height during the whole experiment.

1. Raul has scraped his knee and noticed that after a week it had almost completely healed. Raul wondered how the skin was able to repair itself while looking exactly the same as his non-injured skin. In 3-5 sentences explain how mitosis plays a role in healing skin after injury and is able to maintain the look of the existing, non-injured skin

Injured skin produces C-rays that allow for skin to knit itself back together. These C-rays are always present in cells, but are only activated during mitosis by injured skin. This is why there is sometimes scarring left after injury, as the C-rays are not activated as much as healing occurs.

2. In three to five sentences, explain the advantage of keeping some DNA needed by mitochondria in the cell’s nucleus and some in the mitochondria itself.

Mitochondrial DNA is the small circular chromosome present inside the cell organelle called mitochondria used for energy production. This type of DNA passes from the mother to the offspring. Mitochondrial DNA (mtDNA) has several advantages over nuclear DNA (nDNA):for species identification purposes including a higher copy number a lack of sequence ambiguities from heterozygous genotypes .a faster rate of mutation

3. In 3–5 sentences, construct a summary of the process of gene expression, starting with DNA and ending with proteins

The process of gene expression starts with the transcription of the genetic information in the DNA into genetic codes in the form of messenger RNA.

The messenger RNA then undergoes some processing such as modification of tails and removal of non-coding sequence before the genetic codes are translated to their respective amino acids in a process known as translation.

The amino acids are linked together by peptide bonds and the resulting primary protein structure is folded in specific ways depending on their functions.

Mitosis takes one cell and replicates it into two genetically identical cells. Thus, the correct option for this question is A.

What is Mitosis?

Mitosis may be defined as a type of cell division through which each parental cell is typically divided into two daughter cells. These daughter cells are genetically identical to the parental cell and are mostly diploid in nature.

On contrary, meiosis is another type of cell division in which each parental cell is divided into four daughter cells which are genetically unique to the parental cell. These daughter cells are haploid in nature. This type of division is known as reductional division. It occurs in the germ cells of organisms.

Mitosis may be defined as a type of cell division through which a parental cell is successfully divided into two daughter cells. These daughter cells are genetically identical to the parental cells and generally diploid in nature.

Prophase is the longest phase of karyokinesis. In this phase, the nuclear membrane and nucleolus disappear. In metaphase, the chromosomes are usually lined up in one plane by attaching to the spindle through the centromere.

Anaphase is the smallest phase of mitotic cell division. In this phase, the centromere splits, and chromosomes move to opposite poles. In telophase, the two sets of daughter chromosomes reached opposite poles and are converted into chromatin thread.

Nervous tissue is not found in plant instead they have some different system to respond to stimuli.

Biologists are aware that there are additional ways to process information in addition to our neurological systems and those of other animals, including fish. Plants can react to stimuli despite not having neural systems. For instance, when an aphid bites a leaf, the plant responds by sending an electrical signal from leaf to leaf instructing it to begin defending itself.

However, it's crucial to remember that a plant does not necessarily feel pain when it reacts to injury.

Plants lack nociceptors, the particular receptor types that are hardwired to respond to pain, in contrast to humans and other animals. They naturally lack the brains essential to convert such sensations into actual experiences since they also lack brains.
