Answer:
The five central themes of biology are structure and function of cells, interactions between organisms, homeostasis, reproduction and genetics, and evolution.
Tay-Sachs disease is a rare inherited disorder that progressively destroys nerve cells
in the brain and spinal cord. The allele for having Tay-Sachs is recessive written as t
and the functional allele is written as T. If two heterozygous parents have four
children, how many of the offspring will most likely inherit and develop Tay-Sachs
disease?

Ball and socket joints allow bones to move _____.
back and forth
in all directions
across each other
up and down
Answer:
in all directions
Explanation:
Your shoulder is a ball and socket joint and it can move in all directions as an example.
Answer:
B.) in all directions
Explanation:
Ball-and-socket joints are as the name implies. A ball-shaped end of bone attaches to an indentation on another, the socket. It rotates around in any direction, with an example being the end of your arm that attaches to your torso. This design makes it more mobile than any other type of joint.
pick two structures from an animal cell and explain how they work together and how their functions are vital in keeping the cell alive. the options are cytoplasm, smooth er, nucleolus, nucleus, mitochondria, lysosome, and cell membrane.
Answer:

3. A few years ago the population of male blue moon butterflies on the island of
Samoa declined. One hypothesis for the decline of the male butterflies is that a
parasite infected the cells of female butterflies. The parasite was passed to
offspring through the females' eggs and killed the male butterfly embryos. At
one point during the decline, nearly all the butterflies in the population were
females, but after five years the number of males in the population increased
significantly.
Blue Moon Butterfly.
Which explantion most likely accounts for the increase in the number of male butterflies in the five years after the initial parasite problem. Please anwser this

describe some of destructive action of microbes
Answer:
A microbe is a small living thing too tiny to be seen by the naked eye and includes bacteria, fungi and viruses. Among their destructive actions is causing diseases in human beings and their livestock or plants, destruction of food by causing decomposition which might lead to hunger and other related calamities. Despite this destructive consequences, microbes are also known to have advantageous actions like helping in sewerage treatment, microbes found in the gastro-intestinal tract help in maintaining a good environment for digestion to take place. Microbes also help in ecological balance by causing decomposition of dead matter hence conserve the environment.

What is crossing over in meiosis and how does it ensure genetic diversity?
Answer:
When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. ... It is obviously another source of genetic variation in offspring.

22. Which of the following is not part of Subduction?
a. Volcanic activity
b. Strong earthquakes
c. Melting of the crust into magma
d. The spreading of plates at the subduction zone
Answer:
Where two tectonic plates converge, if one or both of the plates is oceanic lithosphere, a subduction zone will form. An oceanic plate will sink back into the mantle. Remember, oceanic plates are formed from mantle material at midocean ridges.
Explanation:
d. The spreading of plates at the subduction zone

The bacteria in a colony are unable to perform conjugation. How would this hurt the bacterial colony's chance for survival?
A. The bacteria would lose all their RNA.
B. The colony could not produce bacteriophages.
C. The colony would have less genetic variation
D. The bacteria in the colony could not reproduce.
The colony would have less genetic variation. The Bacteria in the colony would be too genetically similar
The bacteria living in a colony is aunable to perform the conjugation as they have less chances of survivial due to the colony is less genetically divere. Thus the option C is correct.
What is conjugation ?This is a process wherein organism of the same species like the bacteria, exchange the nuclear mating materials during a temporary union and are capable of transferring one consent form from one organism to another. Thus the lack of genetic variation will lead to fewer chances of species survival.

The carbon cycle is based on CO2. Therefore, photosynthesis is the opposite of
A
cellular respiration.
B
reproductive cycle.
C
nitrogen cycle.
D
biochemical processes.
Answer:
A Cellular Respiration
Explanation:
This is because Photosynthesis takes CO2 and pushes our Oxygen, while the inverse is true for cellular respiration.

Which product of respiration is considered waste material and leaves the alveoli?
A. oxygen
B. water
C. carbon dioxide
D. carbon monoxide
Answer:
C
Explanation:
Carbon dioxide
Knowing what you know about photosynthesis, explain how the process may reduce
global warming (caused by too much carbon dioxide in the atmosphere).
Through the pores called stomata in their leaves, plants take in carbon dioxide from the atmosphere that they use for photosynthesis. ... But when carbon dioxide levels increase, plants' stomata shrink, releasing less water into the air and reducing the cooling effect.

At what stage of the cycle does the cell copy its DNA?
Answer:
S-Phase
Explanation:
During the S-Phase, the cell replicates its DNA. Interphase is then followed by Mitosis. Mitosis is when the cell separates its two sets of DNA and divides it into two more cells.
Why can light microscopes produce images in their natural color, while scanning electron and transmission electron microscopes only produce grayscale images?
Answer:
there's no color info recored
Explanation:
Answer:
The reason is pretty basic: color is a property of light (i.e., photons), and since electron microscopes use an electron beam to image a specimen, there's no color information recorded.
Explanation:
Scientists discovered that the inner core of Earth is a solid. Explain what evidence supports this thinking. Be sure to include how pressure, temperature, and density play a role. (4 points)
Answer:
The inner core is solid because the inner core consists of a lot of pressure and high temperatures. And the more pressure and high temperatures the more dense the substance gets.
