Answer:
it would be 125
Explanation:
first draw punnet sqaure , by that you will get to know that the probailty of red pink and white flowers is 1:2:1 or 25 % chance of red and white will 50 % for pink flowers.
now ,in the question it is given that total offspring is 500:
for red flowers : 500 x 25% = 125
for white flowers : 500 x 25% = 125
for pink flowers : 500 x 50% = 250

The zebra population would increase because of the increased competition for grass.
The zebra population would decrease because of the decreased competition for grass.
The zebra population would decrease because of increased predation by the lions and cheetahs.

Sunflowers have specialized cells that enable the sunflower to track the
Sun. Which of the following allows the sunflower to move to face the Sun? *
1 point
A.Gravity
B.Electricity
C.Friction
D.Turgor
The sunflower moves to face in the direction of Sun due to the presence of specialized cells. This movement is in response to the electricity. Thus, the correct option is B.
What causes movement of Sunflower?Sunflowers show heliotropic movement. This suggests that there is a learned diurnal rhythm in sunflower due to presence of specialized cells which is followed even in the absence of a strong directional light. Leaves and floral parts of sunflower both exhibit heliotropism. Floral heliotropism is generally controlled by the motor cells which are located just below the flower head.
The movement in sunflower to face the Sun is due to the electricity which is possible due to the movement of ions in the cells. This is called as phototropism.
Therefore, the correct option is B.

Let's bring what you have learned about the carbon cycle, photosynthesis, and cellular respiration and show how they are connected/work together in an ecosystem. Play the role of a carbon atom in an ecosystem. Start with the production, how are you made? And then explain how you transform through different processes. Make sure to include your role in the carbon cycle, photosynthesis, and cellular respiration. There is no set length, as long as you explain the role of carbon in each process.
Answer:
Plants absorb carbondioxide gas from atmosphere whereas respiration releases carbondioxide .
Explanation:
Carbon is present in the atmosphere in the form of carbondioxide gas which is used by the plants in the process of photosynthesis. Plants takes carbondioxide gas from the surrounding air through small openings called stomata and made their own food while on the other hand, carbondioxide gas is released from the body of living organisms in the process of cellular respiration. In cellular respiration, food is broken down with the help of oxygen forming water, carbondioxide gas and energy in the form of ATP molecules.

cell membrane - allows nutrients in and out of the cell
mitochondria - create the energy supply for the cell
organelle - ?
Which important animal cell organelle is missing from the table, and how would this affect the cell?
A. The chloroplast is missing, and the cell would not be able to produce sugar.
В. The cytoplasm is missing, and the cell would not be able to produce energy
C. The cell wall is missing, and the cell would not be able to maintain its rigid structure
D. The nucleus is missing, and the cell would not have genetic information for reproduction
Answer:
An organelle is a structure within the cytoplasm of a eukaryotic cell that is enclosed within a membrane and performs a specific job. Organelles are involved in many vital cell functions. Organelles in animal cells include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles.A

1. Which of the following functions is the cell membrane responsible for? (Choose all that apply) containing the cell U protecting the cell regulating the cell's interaction with its surroundings housing hereditary information
Answer:
The First three answers are correct. (The last one refers to the nucleus which is also inside the cell membrane so i don't know if it's correct)
All of the options are correct for the function of cell membrane.
What is cell membrane?The cell membrane is a thin selectively semi-permeable membrane an outer covering of a cell by surrounding cell cytoplasm.
Proteins and lipids are the major components of cell membrane where as the ratio of protein to lipid in cell membrane may vary depending on types of cells.
The most common lipid in membrane is phospholipid, which form a semi-permeable lipid bilayer.
The function of cell membrane is to protect the integrity of the internal environment of the cell, act as a base of attachment for the cytoskeleton in some organisms resulted in support cell and maintain its shape.
It helps in transport of nutrients into the cell and transport of toxic substances out of the cell due to its selectively permeable nature.

Why might better-insulated buildings make air pollution more of a problem?Why might better-insulated buildings make air pollution more of a problem?
COMPLETE QUESTION:
Why might better-insulated buildings make air pollution more of a problem?
ANSWER: It prevents the passage of waste gases out of the building and inflow of fresh air which can leads to health related issues.
EXPLANATION:
Building insulation reduces the heat surplus in warmer weather condition and reduces the heat loss during cold weather condition.
The negativity that comes with insulating a building is an increased air pollution. In the process of preventing heat loss to the environment by insulating a building, there's a resultant reduction or sometimes blocking of air flow inside the building. This will cause the concentration of waste that are in gas form inside the building, emanated from human activities like cooking (fuel burning), respiration, and other activities.
Overtime, this trapped in of waste gases can leads to sick building syndrome (an health related issue).
