What is the most likely reason that horses and mountain goats have hooves?


They have homologous structures because they have a common ancestor.


They have analogous structures because they have a common ancestor.


These are vestigial structures in both animals because they are not used.


These are similar structures due genetic mutations.





What is the answer to this?

Answers

Answer 1

Answer:

They have homologous structures because they have a common ancestor.

Answer 2

homologous structures because they have a common ancestor is the most likely reason that horses and mountain goats have hooves.

what is homologous structure ?

Homologous structures shoe the same structure, but may have a distinct  function, it indicate a common ancestor.

A homologous structure is an organ or bone seen  common between different animals that demonstrates an anatomical commonality indicating that the animals share a common ancestor.

on the other hand analogous structures where two unrelated species have structures with similar forms or functions due to convergent evolution.

for example of a homologous structure is the wing of a bird and an insect.

electrically charged particles?
A. neutrons are positive, electrons are negative
B. protons are negative, neutrons are positive
C. protons are positive, electrons are negative

Answers

Answer:

C

Explanation:

protons are positive neutrons are neutral and electrons are negative

In an electrically charged particles  protons are positive and electrons are negative.

Neutron has a positive electrical charge?The charge on neutron is zero(no charge). The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another and so atoms are neutral.

Protons have positive or negative?

A proton carries a positive charge and an electron carries a negative charge.so the atoms of elements are neutral, all the positive charges canceling out all the negative charges. Atoms differ from one another in the number of protons, neutrons and electrons they contain.

Which of the following stages of photosynthesis involves carbon fixation, reduction reactions, and the ribulose 1,5-bisphosphate regeneration?


photoreduction

light-independent reaction

light-dependent reaction

first stage photosynthesis

Answers

Answer:

light-independent reaction

Explanation:

Photosynthesis, which is a unique metabolic process where plants synthesize their food (glucose) in the presence of sunlight, occurs in two stages namely: light dependent stage and light-independent stage.

The light independent stage is also known as dark stage because it does not require light to occur. It occurs in the stroma of the chloroplast where ATP and NADPH are used to fix carbon into the production of glucose. This stage involves three major processes:

- Carbon fixation of CO2

- Reduction reactions of G3P

- Regeneration of ribulose 1,5-bisphosphate (RUBP).

Which of the following would cause an error in DNA replication?
A. DNA polymerase pairing A with G
B. DNA ligase connecting chunks of DNA
C. Helicase making a replication fork
D. DNA polymerase checking the DNA

Answers

Answer:

A. DNA polymerase pairing A with G

Explanation:

Adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G).

DNA polymerase pairing A with G would cause an error in DNA replication. The correct option is A.

An error in DNA replication occurs when an incorrect nucleotide is inserted during the replication process.

DNA polymerase is responsible for synthesizing a new DNA strand by adding complementary nucleotides to the existing template strand.

It ensures the accuracy of replication by matching each nucleotide with its complementary partner (A with T and G with C).

If DNA polymerase pairs A with G instead of A with T, it results in a mismatched base pair.

This is considered an error in DNA replication since it introduces a mutation in the newly synthesized DNA strand.

The fidelity of DNA replication relies on the correct base pairing and proofreading mechanisms of DNA polymerase to minimize errors and maintain the integrity of the genetic information.

Thus, the correct option is A.

1. Cross a red bull with a roan cow. Show the Punnett Square:
% Red Cow
% Roan Cow
% White Cow

Answers

Answer:

red cow would be 50% and the same for a roan cow

Cross a Red Bull with a roan cow. The Punnett Square are

% Red Cow =  25% red

% Roan Cow = 50% roan

% White Cow = 25% white

What is a Punnett square?

A Punnett square is a square with a block that is used to see and describe the offspring of the next generation. It contains both genotypes, dominant and recessive, and then there is a crossing over.

Given that, the red cow has genotype RR

A white cow has the genotype ww.

Heterozygous cattle are called Roan (red and white spotted) (RW).

When RR (red) is crossed with WW (white), it results in a roan color.

RR (red)   x    WW (white) = RW (roan)

Two roan individuals are then mated.

RW    x    RW

RR    RW    RW    WW

Offspring

1/4 RR - Red

1/2 RW - Roan

1/4 WW - White

Hence, the offspring are expected to be 25% red, 50% roan, and 25% white.
