Which of the following mammalian body systems work together to regulate internal body
temperature?
Answer:
Circulatory and Integumentary System helps in regulating the body internal temperature.
Explanation:
Scientists believe lichen is the common ancestor for all plants.
Can someone do this quick?
Answer: A.
Explanation:
Palisade mesophyll cells contain the most amount of chloroplasts with an average of 30–70 chloroplasts per cell so they will be number 2 in the graph.
Spongy mesophyll cells contain less chloroplasts than their palisade counterparts to enable them have a larger surface area for gas diffusion.
The guard cells have the least amount of chloroplasts on average and so will be number 1. on the graph.
Describe what might happen to an amino group or a carboxyl group of an amino acid, if that amino acid is placed into water.
Answer:
Amino acids are the monomers that makeup proteins. This amino acid is unionized, but if it were placed in water at pH 7, its amino group would pick up another hydrogen and a positive charge, and the hydroxyl in its carboxyl group would lose and hydrogen and gain a negative charge.
Explanation:
Each amino acid has the same fundamental structure, which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. In the aqueous environment of the cell, both the amino group and the carboxyl group are ionized under physiological conditions, and so have the structures -NH3+ and -COO–, respectively. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. This R group, or side chain, gives each amino acid protein-specific characteristics, including size, polarity, and pH.

D) Circulatory system is not an organ. It refers to a system composed of organs (such as the heart, blood vessels, and blood) that work together to transport substances throughout the body. So, option D is the right choice.
The circulatory system is a complex network of blood vessels, the heart, and blood. It is responsible for transporting oxygen, nutrients, hormones, and waste products throughout the body.
The heart (option A) is an organ that pumps blood and helps circulate it throughout the body.The brain (option B) is an organ that controls various bodily functions, processes information, and regulates the nervous system.The stomach (option C) is an organ involved in the digestion of food.The circulatory system (option D) is not an organ itself but rather a system composed of organs, including the heart and blood vessels, that work together to transport substances.The kidneys (option E) are organs responsible for filtering waste products from the blood and producing urine.Therefore, among the given options, D) Circulatory system is the correct answer as it does not represent an individual organ but a system comprising multiple organs.

Which additional claim can be BEST supported by the evidence from the skulls in the whale fossil record?
O A. The fossil record shows differences in the skulls of the mammals, which shows that they are from three separate species that all
lived at the same time.
B. The fossil record shows similarities in the skulls of the mammals, which shows that they must have had similar habitats and
environments
C. The fossil record shows that some mammals evolved so that their nostrils are further at the top of their skull for better breathing
while in the water.
D. The fossil record does not give enough evidence about the mammals to determine if there is a relationship between the three
skulls.

Answer: The basic theme of whale evolution is the development of large animals from much smaller ancestors, and nowhere is this more evident than in the case of multi-ton sperm and gray whales, whose ultimate forebears were small, dog-sized prehistoric mammals that prowled the riverbeds of central Asia 50 million years ago. Perhaps more intriguingly, whales are also a case study in the gradual evolution of mammals from fully terrestrial to fully marine lifestyles, with corresponding adaptations (elongated bodies, webbed feet, blowholes, etc.) at various key intervals along the way.

How does a loess affect the environment around it?
Answer:
Because loess is deposited from the atmosphere it provides an important geologic archive of past atmospheric circulation that can be used to test atmospheric circulation models
Explanation:
Answer:
Loess often collects in river headwaters, and subsequently gets carried to riverbeds. The buildup can be so dense, that it diverts the water over the adjacent flood plain. This may result in the flooding of rivers.

Explanation:
This pedigree chart tracks the inheritance of a recessive trait that is not sex-linked. Based on the information in the chart, which of the following statements is true about individuals 3 and 4?
At least one is hete rozygous for the trait.
They are both hom ozygous dominant for the trait.
They are both hete rozygous for the trait.
At least one is hom ozygous for the trait.
Answer:
C. They are both heterozygous for the trait.
Explanation:
It is not possible for both parents to be hom ozygous dominant, as that would only produce hom ozygous dominant children, and from the chart they have one child that is recessive.
It is not possible for only one parent to be heter ozygous, as again, that would only produce dominant children.
Lastly, it is not possible for only one to be hom ozygous, because that again would only result in dominant children.
Pairing two heter ozygous parents would result in a 25% chance of a recessive child.
