All humans have 46 chromosomes, 23 derived from either biological parent who has their own set.
Sex chromosomes make gene passing possible through creating offspring.
how does a change in speed cause a wave to change direction
Answer:
Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. ... The wavelength decreases as the light enters the medium and the light wave changes direction.

Which statement below is an accurate claim that can be made based on the lizard table?
A The number of lizards always stays the same.
B The lizard population shifts from being mostly brown to being mostly red.
С The lizard population get more diverse as more generations go by.
D The lizard population shifts from being mostly brown to being most black.
!!
Answer: did you get the right answer ?
Explanation:
The statement is an accurate claim that can be made based on the lizard table, the lizard population shifts from being mostly brown to being mostly black. The correct option is D.
What is a population?The term “population” refers to all citizens who are either permanently residing in a country or who are just passing through. This indicator reveals how many people typically reside in a certain area.
Growth rates are the population changes that occur each year as a result of births, deaths, and net migration.
We can see in the table that the population of lizards or black lizards is increasing, and the brown lizard population is decreasing.
Therefore, the correct option is D. The lizard population shifts from being mostly brown to being mostly black.

What similarities are there in growth of the human population compared to animal/plant populations?
The similarities between the growth of the human population and that of plants and animals can be seen in the fact that in all three instances.
Briefing:With respect to the original number of specimens, the increase happens exponentially.
If there are 100 humans and 50 of each gender, then it is possible for 50 additional people to appear;
Animals and plants both reproduce exponentially compared to the procreative couples that were previously there.
Why is plant population important?Due to the encouragement of apical dominance and the subsequent induction of barrenness, a high plant population ultimately results in a reduction in the number of ears produced per plant of maize. Plant populations should constantly remain at their ideal levels.

When an inducer is added to a medium containing an organism with a metabolic pathway controlled by a repressor, the inducer then Group of answer choices combines with the substrate and blocks induction. does not combine with, but rather functions as a chaperone molecule for, the enzyme-substrate complex. combines with the repressor and activates the repressor. combines with the substrate and activates induction. combines with the repressor and inactivates the repressor.
Answer:
The correct answer is - combines with the repressor and inactivates the repressor.
Explanation:
The role of inducers is to bind with a repressor in a metabolic pathway and cause them to change their shape. This modification of the shape in the repressor structure prevents them to bind with the DNA and the metabolic pathway continues.
So, inducers inactivate the repressors by binding them. For example in Lac operon lactose, an inducer bindswith the repressor and dissociates it from DNA and inactivates the repressor.

Describe DNA synthesis in detail
Answer:
DNA synthesis is the biological process by which a deoxyribonucleic acid (DNA) molecule is created. In the cell, each of the two strands of the DNA molecule acts as a template for the synthesis of a complementary strand.
Answer:
The discovery of the double-helical nature of DNA by Watson & Crick explained how genetic information could be duplicated and passed on to succeeding generations. The strands of the double helix can separate and serve as templates for the synthesis of daughter strands. In conservative replication the two daughter strands would go to one daughter cell and the two parental strands would go to the other daughter cell. In semiconservative replication one parental and one daughter strand would go to each of the daughter cells.
Through experimentation it was determined that DNA replicates via a semiconservative mechanism. There are three possible mechanisms that can explain DNA's semiconservative replication.
(a) DNA synthesis starts at a specific place on a chromosome called an origin. In the first mechanism one daughter strand is initiated at an origin on one parental strand and the second is initiated at another origin on the opposite parental strand. Thus only one strand grows from each origin. Some viruses use this type of mechanism.
(b) In the second mechanism replication of both strands is initiated at one origin. The site at which the two strands are replicated is called the replication fork. Since the fork moves in one direction from the origin this type of replication is called unidirectional. Some types of bacteria use this type of mechanism.
(c) In the third mechanism two replication forks are initiated at the origin and as synthesis proceeds the two forks migrate away from one another. This type of replication is called bi-directional. Most organisms, including mammals, use bi-directional replication.

A student presents an argument as to the importance of lysosomes. Which of the
following statements would be a valid justification to support the student's argument?
A. Lysosomes are needed to digest biomolecules
B. Lysosomes are needed to store energy
C. Lysosomes are needed to package proteins
D. Lysosomes are needed to synthesize proteins
Answer:
A
Explanation:
Lysosomes break down cell parts when needed, and can self-destruct the cell. Organelles are made of biomolecules, the building blocks of life. Therefore, A is the answer. Hope it helps :)

In which division phase is the nucleolus formed and spindle fibers broken down?
A) anaphase
B) prophase
C) metaphase
D)telophase
Answer:
Prophase
Explanation:
During prophase, the nuclear envelope and nucleolus are dissolved and the chromosomes condense. The centrioles and spindle fibers begin to form at opposite poles of the cell.
Answer:
telophase
Explanation:
Spindle fibers disperse as the chromosomes are separated and become housed within two new nuclei.

During the winter, purple finches are often seen in Florida. During the summer, purple finches are rarely seen in Florida. Explain why this change occurs between the two seasons.
Because during summer they don't like to be around urban areas and housing, they are always in coniferous forests; You might see them close to your house but only if they are struggling when the food is scarce, they usually migrate from Canada to grounds to winter widely across central and Southeastern U.S. which includes Florida; but on summer they prefer to stay in deep and damp coniferous forests.

10. At 100x, you will see a cell that is larger and has a dark shape in it. This cell doesn't look like the others because it is a
white blood cell and it functions to protect your body against microbes. Red blood cells do not have a nucleus. White blood cell
count is used as a diagnostic tool to determine if someone is sick. If you were fighting an infection, would you expect to have
more or less WBC's? Why?
Answer:
More
Explanation:
When your body needs more of a cell, it produces more of that cell. Since WBC’s (white blood cells) are used to fight infections, if you are sick you need more of them. Hope it helps :)

Calculate the percentage of viable cells
102/112x100
Answer:
91.07%
Explanation:
Given the expression
102/112 x 100
This can also be expressed as;
= (2*51)/(2*56) * 100
= 51/56 * 100
= 5100/56
= 91.07%
Hence the percentage of viable cells is 91.07%
