Answer 1

Answer: Stage 1 because, at stage 1 all embryos look similar but as they grow older they start look different depending on their genes

Question 2: Similarities in structure among distantly related species are analogous if they evolved independently in similar environments. They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos.

QUestion 3: Similar body parts may be homologous structures or analogous structures. Both provide evidence for evolution. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants.

A box is pushed a distance of 4 meters with a force of 10 N. How much work has been done?

6 units of work
40 units of work
14 units of work

No work has been done

Answers

The quantity of work done by the box is equal to 40 units of work.

Given the following data:

Distance = 4 meters.

Force = 10 Newton.

How to calculate work done.

In Science, work done is generally calculated by multiplying force and the vertical distance (displacement) that is covered by an object.

Mathematically, work done is given by the formula:

Work done = force × distance

Substituting the given parameters into the formula, we have;

Work done = 10 × 4

Work done = 40 units of work.

If a person were having trouble balancing while walking, which cranial nerve should be tested for damage

Answers

Answer:

vestibulocochlear nerve

Explanation:

The Vestibulocochlear nerve( V||| cranial nerve) should be tested in a person who is having trouble balancing while walking.

What is Vestibulocochlear nerve?

The Vestibulocochlear nerve has two components within a single trunk: the vestibular nerve, which innervates the semicircular canals of the inner ear and is involved with equilibrium, coordination, and orientation in space, and the cochlear nerve, which innervates the cochlea and subserves hearing.

Dysfunction of the vestibular system results invertigo, the sensation of environmental motion. On examination, patients with vestibular nerve dysfunction typically have nystagmus, in which the fast component is directed away from the affected nerve. With their arms outstretched and eyes closed, their limbs tend to drift toward the injured side.

Functions of vestibulocochlear nerve:

The primary function of the vestibulocochlear nerves (VIII) is a special sensory, but of two types.The vestibular nerve handles balance and equilibrium, while the cochlear nerve is responsible for hearing.

DNA typing is based on analyzing parts of the genome that don't really affect other genetic functions.
A. True
B. False​

Answers

The question proposed is in fact false, given that the variations being analyzed do in fact affect the individual.

Why is this question false?

DNA typing uses the detection of polymorphisms to identify an individual. These polymorphisms are variations in the genetic code that are considered to be normal. These variations are said to not be harmful nor beneficial but do in fact impact the rest of the genome in very subtle ways.

Therefore, we can confirm that the question proposed is in fact false, given that the variations being analyzed do in fact affect the individual.

Answers

The properties of the gas in each test tube can be used to tell whether the gases are the same or different, because depending on the substance, chemical reactions will occur.

What do you think might happen when a gas is exposed to a small flame?

This happens in the flame test, which is based on the fact that when a certain amount of energy is supplied to a certain chemical element (in the case of a flame, energy in the form of heat), some electrons in the last valence shell absorb this energy.

Moving to a higher energy level, producing what we call an excited state. When one of these excited electrons returns to the ground state, it releases the energy previously received in the form of radiation.

With this information, we can conclude that the properties of the gas in each test tube can be used to know if the gases are the same or different, because depending on the substance, chemical reactions will occur.
