Mutations and natural selection cause adaptations. Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations.

kicyunya [14]

Muscular exercise presents a dramatic test of the body's homeostatic control systems because it results in large amounts of heat production.

Homeostatic control systems- A body's physiological ability to maintain a steady internal environment in response to changes in the external environment is known as homeostasis.

Heat Production- The term "thermogenesis" refers to the process through which energy is lost by producing heat with specialization.

Energy- In biology, cells frequently store energy in macromolecules, especially lipids and carbohydrates (sugars). When chemical bonds are formed, such as during the redox reactions of cellular aerobic respiration, energy is released.

Redox Reactions- A reaction that happens when an oxidizing material and a reducing substance come into contact.

8. The look and feel of a rock's surface is its

Mariana [72]

Texture

Explanation:

The look and feel of a rock's surface is its texture.

The texture of a rock determines how it looks and feels to touch.

Textures of a rock are a function of the arrangement of minerals in them.
The shape, orientation and alignment of the mineral grains determines how the rock will feel and look.
Coarse texture in rock implies that the minerals in rocks are visible to the naked eyes and have a gritty feel
Rock textures tells us about the conditions of formation of a rock.

Camel humps are an adaptation for _______.. a.. storing water. b.. regulating body heat. c.. carrying riders. d.. all of the abo

Fofino [41]

The correct answer is:

b regulating body heat.

Explanation:

Camels have humps on their backs as rooms to store fat. It is this fact that they live off when food and liquid are scarce. A well-fed camel in good shape has a firm, upright hump. After a long, exhausting wilderness journey the corresponding camel will have a hump that does floppy and bent over to one side.e. Concentrating body fat in their humps reduces heat-trapping.

A population of 100 tigers has 30 with horizontal stripes. Using pedigrees, you ascertain that horizontal striping is caused by

bixtya [17]

Assuming that this population is in Hardy-Weinberg equilibrium, we can sayt that the probability that, given enough time, all tigers in the population will have horizontal stripes is 30% = 0.3.

--------------------------

Available data:

Population size, N = 100 tigers
Number of Tigers with horizontal stripes = 30
Horizontal stripes is caused by an autosomal recessive mutation.

We need to know the probability that all tigers in the population will have horizontal stripes, which is the recessive phenotype.

We assume that the population is in Hardy-Weinberg equilibrium, so there should be no evolution.

Since the population is in H-W equilibrium, the allelic, genotypic and phenotypic frequencies will remain the same generation after generation.

Now, we will calculate the allelic and genotypic frequencies of horizontal striped individuals in the population.

There are 100 individuals, and only 30 have horizontal stripes.

So, the phenotypic frequency, F(HS) is 30/100 = 0.3 = 30%

Since this is a recessive phenotype, this value equals the genotypic frequency, F(hh) = 30%

Finally, we can get the allelic frequency by taking the square root of this value.

F(hh) = q² = 0.3

f(h) = q = √0.3 = 0.55 = 55%

According to these calcs, the probability for the fixation of the recessive allele is 55%, and the probability that all individuals express the recessive horizontal stripes phenotype is 30%.

Describe and explain how blood flows from the foot to the lungs.

Natali5045456 [20]

Answer:

lungs:

The blood first enters the right atrium.

The blood then flows through the tricuspid valve into the right ventricle.

When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.

The pulmonary artery carries blood to the lungs where it “picks up” oxygen.

It then leaves the lungs to return to the heart through the pulmonary vein.

The blood enters the left atrium.

It drops through the mitral valve into the left ventricle.

The left ventricle then pumps blood through the aortic valve and into the aorta. The aorta is the artery that feeds the rest of the body through a system of blood vessels.

Blood returns to the heart from the body via two large blood vessels called the superior vena cava and the inferior vena cava. This blood carries little oxygen, as it is returning from the body where oxygen was used.

The vena cavas pump blood into the right atrium and the cycle begins all over again.
