I hope this helps you :)
Explanation:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
The statement that describes the best evidence that two species share a recent common ancestor is that the species have similar DNA sequences, which is present in Option D, as the DNA is the genetic material.
What role does the DNA sequence play in evolution?DNA sequence comparisons have become an increasingly important tool in determining evolutionary relationships between organisms, and after comparing the DNA sequences of different organisms, scientists can determine the degree of similarity between them such as similarities in size, diet, or ecosystem may indicate some degree of similarity between two species, but they do not necessarily provide evidence for a recent common ancestor.
Hence, the statement that describes the best evidence that two species share a recent common ancestor is that the species have similar DNA sequences, which is present in Option D.

Which country loaded botulism toxins into bombs? Why is botulism of less concern than anthrax or plague?
Answer:
Botulism is a rare, but life threatening infection caused by the bacteria Clostridium botulinum which spreads through contaminated food, soil, or through open wounds. Ingestion of bacterial spores and toxins are the main reasons behind the symptoms. Symptoms vary depending on the type of botulism. Medications and infected tissue removal methods are available to remove the bacterial toxins.

Which phrase is associated with asexual reproduction but not sexual
reproduction?
Answer: B. Genetically identical offspring
Explanation:
Asexual reproduction that means the parent organism will split into two organisms, and that there will be no mixing of the DNA, as it is the case in case of the sexual reproduction which mixes up the DNA. Therefore the child and the parent organism will contain exactly the same genetic material.

Fish or mammals? Argumentation
While mammals are better suited for life on land due to several advantages, fish have several adaptations that make them suitable for life in water.
Write the argumentation between fish and mammals?Both fish and mammals are diverse groups with their own specialized adaptations and traits, making direct comparisons between them challenging. Here are some arguments for and against each, though:
Fish:Argument for: Fish have streamlined bodies that make swimming more effective and gills that allow them to extract oxygen from the water, making them well adapted to living in water.
Argument against: Fishes often have less complex and intellectual anatomy and behavior than mammals.
Mammals:Arguments in favor of mammals: Mammals have a greater range of body size and form than fish and adaptations for movement, such as the ability to run, jump, or climb.
Arguments Against: Due to their low buoyancy and inefficient swimming bodies, mammals are less adapted to living in water than fish.
The ultimate determination of which is "better" - fish or mammals - depends on the context and standards being used. Both groups have evolved to occupy a wide variety of ecological regions, but each has its own distinct advantages and disadvantages.
Therefore, while mammals are better suited for life on land due to several advantages, fish have several adaptations that make them suitable for life in water.

A student boiled a pot of water on the stove until there was nothing left. If he started with 100 grams of water, how many grams of water vapor did he produce?
Answer:
100 grams
Explanation:
If there is nothing left that means that all of the 100 grams have become water vapors
He produced 100 grams of water vapor in such a way that nothing was left, which means that all the water vapor of 100 grams has become.
What is Water vapor?Water vapor is also called aqueous vapor is defined as the gaseous phase of water which is a state of water within the hydrosphere. Water vapor can result from the evaporation or boiling of liquid water, or from the sublimation of ice that is transparent, as are most components of the atmosphere.
When water absorbs a sufficient amount of heat it becomes a gas known as water vapour, where the process is called evaporation. The water vapor (steam) mixes with the air and appears as water boils in a teapot and escapes into the air.
Thus, the student produced 100 grams of water vapor in such a way that nothing was left, which means that all the water vapor of 100 grams has become.

Explanation:
if two chromosome have equal length and size , and different in gene number would severity of chromosomal abnormalities in this two chromosome are equal?
Answer:
Unequal.
Explanation:
The severity of chromosomal abnormalities in these two chromosome are unequal that are equal in length and size but unequal in gene number are because the gene number are different from one another. If the size of gene increase or decrease from the normal range then it will leads to chromosomal abnormalities in the cell so the cells that has normal gene number has normal chromosome as compared to those cells where abnormal gene is present so the chromosomes are abnormal.

Goiters may occur due to iodine insufficiency, but other causes are possible. Which of the following would NOT tend to result in increased size of the thyroid gland?
A. High levels of thyrotropin releasing hormone.
B. High levels of thyroid stimulating hormone.
C. High levels of thyroxin and triiodothyronine.
D. All of the above would tend to increase the size of the thyroid gland.
E. None of the above would tend to increase the size of the thyroid gland.
Answer:
Option A
Explanation:
Thyroid is primarily caused by lack of iodine but there are other reasons as well that lead to increased size of the thyroid gland. Some of these reason is
a) over- or underproduction of thyroid hormones
b) Nodules in the glans
Some times, due to overstimulation immune system itself attack the thyroid gland thereby producing excess thyroxine and hence causing the thyroid to swell

Homeostasis is the ability of the body to maintain internal balance despite changing external conditions. How does the respiratory system help maintain homeostasis? The respiratory system helps release hormones to control body processes. The respiratory system helps release unwanted heat and water from the body, The respiratory system produces white blood cells that kill disease causing organisms. The respiratory system releases enzymes that help in the break down of food.
Answer:
b on edge
Explanation:
its right
The respiratory system helps release unwanted heat and water from the body, maintaining homeostasis.
What is homeostasis?" A state of balance among all the body systems needed for the body to survive and function correctly."How respiratory system maintain homeostasis?Respiratory system helps to remove carbon dioxide and excess heat from our body and maintains our blood pH.During respiration, carbon dioxide reacts with water to form a carbonic acid in presence of enzyme carbonic anhydrase. It further dissociates into bicarbonate and H+ ions. This reaction are in equilibriumWhen the level of H+ ions increases, the pH level increases. This will signal respiratory system to release more carbon dioxide. This will result in formation of carbon dioxide and decrease level of H+ ions which will result in increase blood pH.When we breathe out, the moisture from the tissue are also expelled.Hence, the respiratory system helps release unwanted heat and water from the body.
