Humans and gorillas have one different amino acid in their hemoglobin
sequence. What does this say about the evolution of these two species?
A. Gorillas recently evolved from humans.
B. They have no common ancestors.
C. They probably have
recent common ancestor.
O D. They are probably the same species.
SUBMIT
Answer:
they probably have a recent common ancestor
Explanation:
They probably have recent common ancestor. Therefore, option (C) is correct.
What is evolution?Evolution is the process by which species change over time, usually through natural selection. The theory of evolution is supported by a vast body of evidence from many fields, including genetics, paleontology, and comparative anatomy.
Evolution occurs because of changes in the genetic code of organisms, which can be caused by mutations, gene flow, genetic drift, and natural selection. Over time, these changes can accumulate and result in the development of new species from ancestral forms. Evolution is a slow process that occurs over many generations, and it has been responsible for the incredible diversity of life on Earth, from the simplest bacteria to the most complex animals and plants.
The fact that humans and gorillas have one different amino acid in their hemoglobin sequence suggests that they have a recent common ancestor. This is because the hemoglobin protein plays an essential role in carrying oxygen in the blood and is highly conserved across species that share a common ancestor.

how do animals survive in both water conditions
Answer:
they have adapted to the temperatur since water trafers water faster than air. (more info below)
Explanation:
animals also have adaptations to temperature control, as water transfers heat faster than air. At the end of the day, aquatic animals have a lot of adaptations for moving in the water, such as a streamlined design, flippers, and a swim bladder, which acts like a fish ballast.

Most scientists agree that saturated fats contribute to high levels of “bad” cholesterol, while monounsaturated fats and polyunsaturated fats lower this type of cholesterol. The table below shows data about fats in some common foods.
Food (14 g) Saturated fat (g) Monounsaturated fat (g) Polyunsaturated fat (g)
Canola oil 1.0 8.9 3.9
Margarine 1.6 5.4 3.4
Olive oil 1.9 9.9 1.4
Lard 5.0 5.8 1.4
Butter 7.9 3.7 0.5
Joyce and Linda are identical twins who are 50 years old and enjoy exercising daily. Joyce avoids eating any dairy or animal products and eats granola made with canola oil for breakfast. Linda prefers rich foods, and eats bacon, eggs, and buttered toast each morning. Which statement describes a logical inference that can be made from the provided information?
a)Butter has higher levels of saturated fats in it than canola oil.
b)Linda and Joyce both have high levels of “bad” cholesterol.
c)Butter contains a small amount of polyunsaturated fats.
d)Linda has a higher level of “bad” cholesterol than Joyce.
Answer: D: Linda has a higher level of "bad" Cholesterol than Joyce
Explanation: From the first sentence Saturated fat contributes to high level of bad cholesterol. Buttered food, bacon ( Lard) are significantly high in saturated fat which contributes to high level of bad cholesterol and that's what Linda is eating. Joyce on the other hand avoids animal products and feeds on granola from Canola oil which is low in saturated fat.
The logical conclusion base on this diet is Joyce has low level of bad cholesterol while Linda has high level of bad cholesterol

How does the process of ridge push cause the formation of new oceans?
Answer:
Explanation and answer below
Explanation:
Ridge push causes a rift valley; as the plates move apart, a new ocean basin forms, filling with water and eventually becoming a mature ocean. Ridge push causes a convergent plate boundary; as the plates move together, new islands form, which “trap” water between them, causing an ocean to form.

Anna applies a force of 84n Nto lift her baby nephew 2.0 m. How much work
does Anna do? Answer
Answer:
168 J
Explanation:
Work can be calculated using the following formula.
w=f*d
where w is work, f is force, and d is distance.
Anna applied a force of 84 Newtons, and lifted the baby 2.0 meters.
f=84 N
d=2 m
Substitute these variables into the formula.
w=84 N* 2 m
Multiply
w=168 N-m
A N-m is the same as a Joule, or J.
w= 168 Joules
Anna does 168 Joules of work.
Considering only the values of 0 for which the expression is defined, which of the following is equivalent to the expression

Select the correct answer below:
O-tan

O-cot0csc0sec0
O tan0
Answer:
A. [tex]-tan\theta[/tex]
Explanation:
Given
[tex]sin\theta\ .\ tan\theta\ .\ sec\theta .\ cot(-\theta)[/tex]
Required
Simplify
[tex]sin\theta\ .\ tan\theta\ .\ sec\theta .\ cot(-\theta)[/tex]
Substitute [tex]\frac{1}{cos\theta|}[/tex] for [tex]sec\theta[/tex]
So, the expression becomes
[tex]sin\theta\ .\ tan\theta\ .\ \frac{1}{cos\theta} .\ cot(-\theta)[/tex]
Rearrange the above expression
[tex]sin\theta\ .\ \frac{1}{cos\theta}\. \ tan\theta\ .\ cot(-\theta)[/tex]
[tex]\frac{sin\theta}{cos\theta}\. \ tan\theta\ .\ cot(-\theta)[/tex]
From trigonometry;
[tex]tan\theta = \frac{sin\theta}{cos\theta}[/tex]
So, we have
[tex]tan\theta\ . \ tan\theta\ .\ cot(-\theta)[/tex]
From trigonometry;
[tex]cot(-\theta) = -cot(\theta)[/tex]
So, the above expression becomes
[tex]tan\theta\ . \ tan\theta\ .\ -cot(\theta)[/tex]
[tex]-tan\theta\ . \ tan\theta\ .\ cot(\theta)[/tex]
From trigonometry;
[tex]cot\theta = \frac{1}{tan\theta}[/tex]
So, we have
[tex]-tan\theta\ . \ tan\theta\ .\ \frac{1}{tan\theta}[/tex]
Express as a single fraction
[tex]\frac{-tan\theta\ . \ tan\theta }{tan\theta}[/tex]
[tex]-tan\theta[/tex]
Hence, [tex]sin\theta\ .\ tan\theta\ .\ sec\theta .\ cot(-\theta) = -tan\theta[/tex]
Why xylem and phloem are called complex tissues? How are they different from one another?
Answer:
Xylem and phloem are called complex tissues because they are made up of more than one type of cell working together as a unit. The xylem transports H2O and minerals upward from the roots to the leaves, and is composed of tracheid cells which are dead at maturity (no active nucleus, makes the tree stem hard). If plants don't have xylem, they will stay lower to the ground as it is responsible for making the tree grow upward. The ends of the xylem tubes are tapered (pointed), materials are passed along one cell at a time, and the tubes are narrow and continuous. The phloem transports sugars and proteins downward from the leaves to the stems and storage roots. The cells that make up the phloem are called sieve tubules and companion cells. The companion cells have the nucleus and the sieve tubules contain the cytoplasm.
Explanation:
My teacher helped us remember using the phrase "phloem down the river" because it sounds like 'flowing down the river' (to help remember that phloem transports downward and xylem transports upward.)
