Answer:

FALSE

Explanation:

In plant and animal adaptations, form follows function. it is true because all forms of organisms give adaptive advantages.

Living beings tend to have adaptations according to the environment in which they live. Plants in hot and dry climates generally have their leaves reduced, or even modified into thorns, as a way of reducing the contact surface and thus avoiding transpiration.

Whit this information, we can conclude that in plant and animal adaptations, form follows function. it is true because all forms of organisms give adaptive advantages.

Answer: The botanist should use sexual reproduction to make the new plants because asexual reproduction will only produce spider plant offspring with the same types of traits as the parents.

Explanation:

Assuming that the botanist already has spider plants with larger flowers in their nursery, in order to develop a large number of the plant based on the same traits, asexual reproduction method should be used.

Asexual reproduction method is preferred because:

Sexual reproduction leads to variation such that daughter plants will not have exactly the same traits as their parents. The number of plants that can be produced sexually is also limited.

Answer:

C. The mountain has wider range of environments.

Explanation:

Steep mountain habitat have a higher rate of speciation than a large, open grasslands habitat The mountain has wider range of environments.

There are various locations and climates on earth where grassland environments can be found. Depending on where in the world they are and the type of climate there, they may also be referred to as prairies, savannahs, steppes, or pampas.

Because there are few places for animals to hide from predators in grasslands, they have developed underground burrows or grown tall enough to look over thick grasses and shrubs.

Many grasslands have been used for farming because they are suitable for raising crops and providing food for cattle. Yet, this means that grassland animals can no longer reside there.

Therefore,  Steep mountain habitat have a higher rate of speciation than a large, open grasslands habitat The mountain has wider range of environments.

Answer:

253.585 square inches

Explanation:

The figure can be decomposed into 2 rectangles and a quarter circle.

Area of the figure = area of rectangle 1 + area of rectangle 2 + area of ¼(circle)

✔️Area of rectangle 1 = Length × width

Length = 10 in

Width = 6 in

Area of rectangle 1 = 10*6 = 60 in²

✔️Area of rectangle 2 = Length × width

Length = 10 in

Width = 6 + 7 = 13 in

Area of rectangle 2 = 10*13 = 130 in²

✔️Area of ¼(circle) = ¼(πr²)

r = 9 in

π = 3.14

Area of ¼(circle) = ¼(3.14*9²) = 63.585 in²

✅Area of the figure = 60 + 130 + 63.585 = 253.585 square inches

Answer:

A tripeptide

Explanation:

Alanine (Ala), Glycine (Gly) and Valine (Val) are amino acids, i.e., organic molecules that contain at least an amino (–NH2) and one carboxyl (–COOH) functional group. The amino acids held together by peptide bonds, which are formed by a carboxyl group of one amino acid and an amino group of another one, in order to form a peptide. Thus, a tripeptide is a peptide composed of three amino acids joined by two internal (and sometimes three) peptide bonds. In the case above described, the tripeptide formed by the binding of Glycine, Alanine, and Valine can be abbreviated as Gly-Ala-Val (i.e., in this order).

Answer:

Internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur. External regulators speed up or slow down the cell cycle.

Explanation:

Internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur while external regulators speed up or slow down the cell cycle.

Proteins are large and complex molecules which play many critical roles in the body. Proteins do the work in cells which are required for the structure, function, and regulation of the body's tissues and organs.

Proteins are made up of many smaller units called amino acids, which are linked together in long chains. There are 20 different types of amino acids that can be linked to make a protein.

The sequence of amino acids determines each protein's unique 3-dimensional structure and its specific function. Amino acids are coded for by a combination of three DNA building blocks (nucleotides), which are determined by the sequence of genes.

Thus, internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur while external regulators speed up or slow down the cell cycle.

Answer:

The correct answer would be - "bacterial populations evolve in response to the selection pressure imposed by antibiotics".

Explanation:

The given information provided in the question about the bacterial infection supports the hypothesis that the bacterial population shows the evolution in response to the selection pressure caused by the antibiotics due to the fact that bacteria increased resistance gradually with time. This resistance towards antibiotics increased the percentage of bacterially infected children in the late 1980s and early 1990s.

In this case, the population of bacteria having resistance genes is selected to evolved selected to increase their offsprings.

Answer:

The reactions of glycolysis that are shared with those in gluconeogenesis (ie use the same enzymes) are those that Are regulated steps.

Explanation:

Glycolisis and gluconeogenesis are two mechanisms related to the carbohydrates metabolism.  Sometimes they are considered reverse processes. However, they are different because of the control points they have where reactions are irreversible.

Glycolisis and gluconeogenesis share 7 common reactions, that are reversible. Thses reactions are coordinated and regulated by F-2 and 6-BP as the answer to the hormonal action.

Glycolisis happens in the muscle, while Gluconeogenesis happens in the liver. Together they form the "Cori Cycle".

Answer:

a. True

Explanation:

The genome can be defined as the complete set of genetic information of an organism which is responsible to produce all the biological components required to carry out its metabolic functions (i.e., development, growth, reproduction, etc). These genes are transcriptionally expressed to produce mRNAs which are subsequently used to synthesize specific proteins (i.e., enzymes and structural proteins) by the process of translation. All organisms (i.e., either unicellular or multicellular organisms) exhibit specific gene expression programs by which such genes are regulated over time. Within the cell, gene regulation is essential to carry out biological processes ranging from development and differentiation to cell cycle arrest. These gene expression programs are acutely regulated via genetic (e.g., transcription factor binding) and epigenetic (e.g., DNA methylation) mechanisms, which work together in order to turn on/off genes during development.

-The colonies strongly objected to these laws and taxes.

-They wanted England to have no control over them.

-For ten years before the war actually started, there was a lot of tension between England and the colonies.

-The colonies had no central government at the beginning of the war, so delegates from all the colonies were sent to form the first Continental Congress.

-George Washington, a former military officer and wealthy Virginian, was appointed Commander in Chief of the Continental Army.

-Members of the Continental Congress wrote a letter to King George of England outlining their complaints and declaring their independence from England.

-On July 4, 1776, the Continental Congress adopted the Declaration of Independence, in which the colonies declared their independence from England.

-The war ended in 1783, and the United States of America was born.
