Which Sentence is true about cells?
(A) All cells do the same job
(B) All cells are the same inside.
(C) All Living things are made of cells.
(D) All living things have the same number of cells.
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Rudolf Virchow later made important contributions to this theory.

Which of the following statements describes the structure of the plasma membrane?
a It is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward.
b Protein molecules make up the membrane, which makes it a strong structure.
c The plasma membrane is made mainly from carbohydrates that give the cell energy.
d It is made primarily of cholesterol that allows the cells to communicate with others.
Answer:
A. It is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward.
Explanation:
The plasma membrane (also known as the cell membrane) is a membrane that separates the cell's interior from the environment that surrounds it, protecting it. It consists of lipids, proteins, and carbohydrates.
Its main component are phospholipids that create a bilayer. Phospholipids consist of two hydrophobic tails and a hydrophilic head and are arranged so that the tails face inward and the heads outwards.
This is why option A is the correct one.
You can see an image of the cell membrane's structure to help you visualize this below:

During photosynthesis, plants produce ___ and oxygen from the ___ of solar energy, water, and carbon dioxide.
Answer:
1. Glucose
2. Conversion
Explanation:
During photosynthesis, plants produce glucose and oxygen from the light of solar energy, water, and carbon dioxide. This process is called photosynthesis.
What is photosynthesis?Photosynthesis is a process that takes place in green plants because they have chlorophyll pigment. Chloroplast is the organelle that is present in green plants. This organelle has chlorophyll pigment that carries out the photosynthesis process.
In photosynthesis, water is taken from the soil, carbon dioxide is taken from the atmosphere, and with the help of sunlight, glucose and oxygen are formed in the chloroplast. Due to this, plants are called producers.
Photosynthesis releases oxygen into the atmosphere, which is required by all living organisms. Organisms take in oxygen and release carbon dioxide into the environment. This is called the respiration process.
In the grassland ecosystem, the plants do photosynthesis. In the ocean's ecosystem, phytoplankton do photosynthesis. Different consumers depend on these producers for food.
Hence, plants produce glucose and oxygen from solar light energy, water, and carbon dioxide.

Please help me!! what is the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy?
Answer:
3/16
Explanation:
This question involves two genes coding for pea shape and pea color. The alleles for yellow color (Y) and round seeds (R) are dominant over the alleles for green color (y) and wrinkled seeds (r).
In this cross between two heterozygotes: RrYy × RrYy, the following allele combinations are produced in the gamete of each parent: RY, Ry, rY and ry. Using these gametes in a punnet square (see attached image), the following offsprings are produced:
9/16 of Round, yellow offsprings (R_Y_)
3/16 of Round, green offsprings (R_yy)
3/16 of Wrinkled, yellow offsprings (rrY_)
1/16 of wrinkled, yellow offsprings (rryy)
Hence, the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy is 3/16.

What happens during the first two stages of cellular respiration?
Answer:
Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. ... Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.
