A. They develop from the same embryonic
tissue.
Human
Bird
B. They are the most important sets of
bones.
C. They have no current use.
D. These animals do not share a common
ancestor.
Answers
Answer: its A
Explanation:
They have no current use, because they were passed down from a common ancestor, homologous structures are those that are comparable in related organisms, hence option C is correct.
What is homologous structures?The descendants of these structures may or may not carry out the same purpose. Tetrapods' four limbs are an illustration of homologous features. All four limbs are present in birds, bats, mice, and crocodiles.
Bony fish such as sharks do not. Tetrapods evolved four limbs, and their descendants have carried on this trait.
As a result, the presence of four limbs is a homology. The upper arm of both humans and cats consists of just one bone, which we refer to as the humerus, and two forearm bones, the radius on the more medial side and the ulna on the more lateral side.
Therefore, option C is correct.

Answers
30.Water molecules are polar because they have positive and negative ends, rather like little magnets. Most lipids are non-polar (having no charged areas) or only slightly polar, with a very few charged areas. Water mixes with hydrophilic (water-loving) compounds by sticking to their charged groups.
31.Lipids are detected using the emulsion test. This is what happens: The test substance is mixed with 2 cm 3 of ethanol. An equal volume of distilled water is added.
32.In addition to carbon, hydrogen, and oxygen atoms, all proteins contain nitrogen and sulfur atoms, and many also contain phosphorus atoms and traces of other elements. Proteins serve a variety of roles in living organisms and are often classified by these biological roles.
33.amino acids
For example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein
34.Peptide Bonds
Section 3.2Primary Structure: Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).
35.A polypeptide is a single linear chain of many amino acids (any length), held together by amide bonds. A protein consists of one or more polypeptides (more than about 50 amino acids long). An oligopeptide consists of only a few amino acids (between two and twenty).

A. the deer population will decrease.
B. the plant population will increase.
C. the predator population will decrease.
D, the smaller herbivore population will decrease.
Answers
The awnser is D because if we didnt kill deer there would be a increase in population and a decrease in the food they eat
Explanation
BRAINLIEST PLEASEIf deer are not hunted legally every season, a potential result is that the deer population will increase, not decrease, due to lack of control measures.
What are the various negative impacts for this condition ?This can have negative impacts on the ecosystem, such as overgrazing of vegetation and competition for resources with other herbivores. Additionally, an increase in the deer population can also lead to an increase in the predator population, as more predators may be attracted to the area to prey on the abundant deer.
If deer are not hunted legally every season, the deer population may actually increase. This is because hunting can be an effective way to control deer populations, and without it, there may be no natural predators to control their numbers. As a result, the deer may overgraze vegetation and compete with other herbivores for resources, leading to a decrease in the plant and smaller herbivore populations.
An increase in the deer population can also lead to an increase in the predator population, as more predators may be attracted to the area to prey on the abundant deer. This can have both positive and negative impacts on the ecosystem, as it may increase biodiversity but also lead to competition and potentially negative impacts on other species.
Overall, the management of deer populations is important to maintain a healthy and balanced ecosystem. This can involve regulated hunting, predator control, and other measures to control deer populations and minimize negative impacts on the ecosystem.
Therefore, the correct answer is not listed in the options provided, but of the options listed, the closest answer would be A. the deer population will decrease.

What is the difference between scientific theory and law?
Answers
Answer:
Explanation:
Like theories, scientific laws describe phenomena that the scientific community has found to be provably true. Generally, laws describe what will happen in a given situation as demonstrable by a mathematical equation, whereas theories describe how the phenomenon happens.
1. Which statement is scientifically accurate? A. "Don't let the cold energy out of the fridge!" b. "Don't let the energy into the fridge!" Explain in terms of energy transfer.
Answers
Answer:
The accurate statement is b. "Don't let the energy into the fridge!"
Explanation:
Heat is energy. Inside a fridge there is lower heat - lower energy - than the surroundings. The spontaneous transference of energy is always from a place with higher energy (hot) to a place with lower energy (cold). So, as the frigde is cold, the heat is transferred from the surroundings to the fridge.

What is number of ATP molecules produced per molecule of glucose when Pyruvate is used to produce NADH, ATP, and FADH2
Answers
Answer:
2 ATP molecules.
Explanation:
This question is describing KREB'S CYCLE, which is the second stage of aerobic cellular respiration that occurs in the mitochondrion. In the Kreb's cycle, also known as tricarboxylic acid cycle, pyruvic acid (product of glycolysis) is oxidized to produce NADH, FADH2, ATP and CO2 as products.
In a nutshell, per glucose molecule that begins the respiration process (glycolysis), 2 molecules of ATP are produced alongside 3 NADH and 1 FADH2 molecules in the Krebs cycle. Note that, the electron carriers (NADH and FADH2) are used in the electron transport chain.

Kelly's teacher asked the class to explain how the rough endoplasmic reticulum works with the nucleus to maintain homeostasis.
Which student's statement is BEST evaluated by the claim and why?
biology
Answers
Answer:
C
Explanation:
Because the roughly endoplamsic works with nucleus and it does so to maintain homeostasis it has to.
Jacob clarified that when issues develop synthesize proteins in the rough endoplasmic reticulum signals the nucleus can receive signals from the reticulum to control the synthesis of proteins.
What is rough endoplasmic reticulum?Because it produces proteins for the cell, the rough ER (endoplasmic reticulum) aids in the maintenance of homeostasis. The role of the rough ER is to produce proteins that are either going to be secreted or are going to other membrane-bound organelles in the endomembrane system.
The ER has a special degree of control over protein synthesis because of its close proximity to the cell nucleus.
When issues with protein synthesis and folding arise, the rough ER can quickly transmit signals to the nucleus, which affects the overall pace of protein translation.
Therefore, the nucleus can receive signals from the rough ER to control the synthesis of proteins.
