Under normal conditions, gases diffuse through small holes in the leaves of a plant. when the weather hot and dry, plants may close these openings to conserve water. how are the closures most likely to affect photosynthesis?
A.) They increase the rate of photosynthesis by increasing the amount of water in the leaf
B.) They have little or no effect on photosynthesis because gases do not take part in the process.
C.) they increase the rate of photosynthesis by increasing the amount of oxygen in the leaf
D.) they decrease the rate of photosynthesis by preventing carbon dioxide from entering the leaf
PLEASE HELP ME!! PLEASE ANS THANK YOU!!!
Answer:
A) They increase the rate of photosynthesis by increasing the amount of water in the leaf.
During winter's freezing temperatures, some plants can remove water from their cells to reduce the amount of water that will freeze inside them. Why would plants need to do this
Answer:
The expansion of excess water as it turns to ice inside the cells would break the cells apart
Explanation:
We know that water expands anomalously. It expands between 4- 0°C.
Hence water expands upon freezing. Ice has more volume than liquid water and takes up more space in plant cells.
The expansion of excess water as it turns to ice inside the cells would break the cells apart

D.) light observes the energy that is released by small molecules
PLEASE HELP ME!!! PLEASE AND THANK YOU!!
Answer:
C
Explanation:
ight provides the energy for breaking apart sugars into small molecules. ... They absorb sunlight and transfer the energy to electrons. They form ATP as hydrogen ions cross the thylakoid membrane
Light provides the energy for making small molecules into sugars.
The correct option is B.
What is photosynthesis?Photosynthesis is the process, by which plants make their food.
The process of photosynthesis is
carbon dioxide and water combined with the help of light to produce glucose and oxygen.
The light helps in the synthesis of glucose from water and carbon dioxide.
Thus, the correct option is B. Light provides the energy for making small molecules into sugars.

Determine the temperature of the bar on the fahrenheit scale.
Answer:
Determining bar temperature on Fahrenheit scale -
The temperature of the bar is given as 50 degrees Celsius.
If we know the temperature on the Celsius scale, we can convert it to the Fahrenheit scale.
We know
C / 5 = (F-32) / 9; Where C is the temperature on the Celsius scale and F is the temperature on the Fahrenheit scale.
Now,
50/5 = (F-32) / 9
Or, (F-32) / 9 = 10
Or, F-32 = 90
Or, F = 90 + 32
Or, F = 112 degrees Fahrenheit.
That is, the temperature of the bar on the Fahrenheit scale is 112 degrees Fahrenheit

What is gained from each part of aerobic 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. ... This results in a net gain of two ATP molecules. Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.
Hope this helps..Why are leaves necessary for a plant?
Answer:
PLEASE MARK AS BRAINLIEST!!
Explanation:
Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food. Through pores, or stomata, leaves “breathe” in carbon dioxide and “breathe” out oxygen.

What are the components of a multicellular organism?
Answer:
Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions. In humans, cells differentiate early in development to become nerve cells, skin cells, muscle cells, blood cells, and other types of cells.
Answer:
Because the first multicellular organisms were simple, soft organisms lacking bone, shell or other hard body parts.
Sickle cell anemia is carried on the recessive allele. Normal is dominant. Mary is a carrier for sickle cell and Mike is normal (but not a carrier).
A. What are the chances of Mary and Mike having a sickle cell child?
B. What are the chances of them having a child who is a carrier?
Answer:
A. 0
B. 1/2 or 50%
Explanation:
Let us assume that the sickle cell anemia trait is represented by s and the alternate normal version by S.
Mary, a carrier would have the genotype Ss.
Mike, a perfectly normal person would have the genotype SS.
If both Mary and Mike marry:
Ss x SS
offspring: SS SS Ss Ss
(A) In order to have sickle cell, the two alleles must be recessive. None of the offspring from the cross has two recessive alleles. Hence, the chances of Mary and Mike having a sickle cell child is zero.
(B) From the cross, two out of four of their potential offspring have the trait in heterozygous condition. Hence, the chances of Mike and Mary having a child who is a carrier is 1/2 or 50%.

Answer:
1. binary fission
2.s phase
3.cytokinesis
4 spindle
5.exit from cell cycle
Cell cycle is essential for the cell to divide and grow. The correct answers are 1. Binary fission, 2. S-phase, 3. Cytokinesis, 4. Spindle fibers, 5. Exits from the cell cycle.
1. Binary fission: The parent cell divides into two brand-new daughter cells. The genetic material is split and duplicated into two pieces. Here, the DNA of each daughter cell is duplicated.
2. S-phase: DNA replication and a large portion of DNA repair activities take place in cells during the S phase, which is situated between the G1 and G2 phases of the cell cycle.
3. A cell splits into two daughter cells by physically dividing its cytoplasm through a process called cytokinesis.
4. Spindle fibers: When a cell divides during mitosis and meiosis, spindle fibers are the filaments that make up the mitotic spindle. During nuclear division, they play a major role in transporting and sorting the chromosomes.
5. G0 phase: G0 phase cells do not actively prepare to divide. When cells leave the cell cycle, they enter a quiescent (inactive) state. Some cells briefly enter G0 before the start of G1 is signaled by an outside source.
Therefore, the correct answer is c) binary fission, b) S-phase, c)cytokinesis, d) spindle fibers and e) exit from cell cycle.
