Answers

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.

what is a ecosystem? write 2 to 5 sentences to explain it​

Answers


Ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.

For instance, tropical forests are ecosystems made up of living beings such as trees, plants, animals, insects and micro-organisms that are in constant interaction between themselves and that are affected by other physical (sun, temperature) or chemical (oxygen or nutrients) components.


An ecosystem consists of a community of organisms together with their physical environment.
Ecosystems can be of different sizes and can be marine, aquatic, or terrestrial. Broad categories of terrestrial ecosystems are called biomes.
In ecosystems, both matter and energy are conserved. Energy flows through the system—usually from light to heat—while matter is recycled.
Ecosystems with higher biodiversity tend to be more stable with greater resistance and resilience in the face of disturbances, or disruptive events.

How does a loess affect the environment around it?

Answers

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:


Describe what might happen to an amino group or a carboxyl group of an amino acid, if that amino acid is placed into water.

Answers

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.

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.

Answers

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.

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.
