HELP PLEASE!! pleaseeee
Answer:
2:1
Explanation:
Let the allele for achondroplasia be represented by A.
Since the disease is lethal in AA condition, the two people would rather be Aa.
Aa x Aa
offspring AA Aa Aa aa
The AA offspring does not survive, hence, we are left with 3 children out of which 2 are affected heterozygotes and the remaining 1 is a true-breeding recessive and normal.
The expected ratio of affected to normal offspring is, therefore, 2 to 1.

Connective tissue contains fibroblasts that are responsible for: A. providing a fibrous framework for capillaries. B. synthesis of collagen, elastin, and reticular fibers. C. forming tendons and the fascia that covers muscles. D. filling spaces between tissues to keep organs in place.
Answer:
The correct answer is B.
Explanation:
The fibroblast is a dynamic cell, which exerts tissue functions at the local level and the immune system. Among its main functions is the formation of connective tissue fibers called collagen and elastin; The fibroblast performs other equally important roles such as: The production and maintenance of the fundamental substance in which its fibrous products are embedded, it has the ability to synthesize and phagocytize collagen and extracellular matrix components in connective tissue remodeling processes.

What do you think would happen to the process of cell division if there is a deficiency in the Golgi apparatus's ability to package protein tubule materials?
Answer:
The process of cell division will slow down and the cell will die
Explanation:
Without the golgi apparatus or if its not working as well as it should be there would be no lysosomes or less. Without the lysosomes there will be a lot of junk/trash in the cell and it would have no way to break it down and get it out

Water has the ability to store heat longer than other substances and moderate temperature. This
property allows water in cells to absorb much heat without changing. What benefit does this property
of water provide to organisms?
A. O It provides the ability to dissolve nonpolar compounds.
B.
It provides the appropriate catalyst for chemical reactions
C.
It allows organisms to maintain a stable internal temperature or homeostasis
D. It enables organisms to function with a higher cellular pH
Answer:
A.
Explanation:
Why do people feel fireworks before hearing it?
Answer:
People feel fireworks before hearing it because light travels faster than sound.
Explanation:
We always see the colors of the fireworks before hearing their defeaning sounds. This is because light travels faster than sound, so we can see the light before hearing the sound. An example of this is seeing lightning before hearing thunder. When lightning strikes, the air around it moves very quickly, causing vibrations.

water breaks down into what 3 things during the light reactions
The process in which water is broken down during the light dependent reactions is called photolysis.
Reaction
H₂O-->1/2O₂+2e⁻+2p⁺
Atomic oxygen is released from the water molecule and reacts with another atomic oxygen to form molecular oxygen(O₂)
The hydrogen atom has only one proton and one electron so one hydrogen atom can be written as(e⁻+p⁺) in the water molecule 2 hydrogen atoms are present so there will be 2e⁻+2p⁺
Therefore the three things that result from photolysis are:
oxygenprotonselectronsWhat do plants need in order to perform photosynthesis?
Answer:
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
Explanation:
If more oxygen were made available to cells that had a limited amount of oxygen, what could be the result? Select all that apply.
A.
Anaerobic respiration could occur more quickly.
B.
The cells could begin to perform aerobic rather than anaerobic respiration.
C.
The cells could begin to perform anaerobic rather than aerobic respiration.
D.
The cells’ mitochondria could become involved in the cellular respiration process.

Newton's first law of motion states that an object will remain in motion in a straight line unless compelled to change direction by an external force.
Explain why satellites launched into orbit do not continue moving in a straight line. Make a connection between satellites and planets.
Explanation:
When satellites are launched into orbit, they are able to orbit around planets due to the gravitational force of attraction between the satellite and planet (usually there is no apparent change in motion of the planet because of its relative huge size than the satellite)
This gravitational force is in a different direction than the satellite's motion, therefore it keeps it orbiting around planets and does not continue moving in a straight line.
How does turgor pressure inside a plant, allow the plant to do? Will give brainliest!
Answer:
The turgor pressure provided by osmosis in a hypotonic solution pushes outward on the plant cell wall, which is just what the plant cell needs to maintain its structure.
Explanation:
Answer:
Plant cells need turgor pressure to maintain their rigidity and sturdiness. This is what gives a plant the ability to grow and stand tall. ... The turgor pressure provided by osmosis in a hypotonic solution pushes outward on the plant cell wall, which is just what the plant cell needs to maintain its structure.
Explanation:
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall

which structure allows chromosomes to separate and move during mitosis
what are the possible blood types of a child whose parents are both heterozygous for b blood type
Answer:
I believe the answer is:
If both are BB, the child will be BB. If one is BB and one is BO, the child has a 50% chance of being BB and 50% chance of being BO - both of which result in type B. However, if both parents are BO, there is a 25% chance of BB, a 50% chance of BO, and a 25% chance of OO (which results in type O).
