9) The process of photosynthesis uses the carbon in
carbon dioxide molecules as building blocks for
which type of molecule? (Think (H1706)
Answer:
Explanation:
carbohydrate molecules -
Photosynthesis uses carbon dioxide and water to assemble carbohydrate molecules (usually glucose) and releases oxygen into the air.
The sperm and the ovum are called haploid (as they have only 23 chromosomes) which is half the number of chromosomes seen in all the other human body cells. What is the significance behind the maintenance of this special chromosomal number in the male and female gametes?
Answer:
During the process of meiosis(The process of cell division through which the germ cells such as the reproductive cells are formed), the sex cells produced are haploids (have only 23 chromosomes). This is significant as during the process of fertilization, the nucleus of the sperm (containing 23 chromosomes) and the nucleus of an egg (containing 23 chromosomes too) fuse, hence, retaining the original number of chromosomes in the zygote formed. i.e 46 chromosomes.
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.
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..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%.
At night, a land breeze forms because
A) water releases less solar energy during the day; warm ocean air moves into land.
B) land cools more quickly than water; cool land air moves to replace rising warm air over the water
C) land absorbs less solar energy during the day; cool land air moves to replace rising warm air over the water
D) water absorbs more solar energy during the day; cool land air moves to replace rising warm air over the water
Answer:
B) land cools more quickly than water; cool land air moves to replace rising warm air over the water
Explanation:
During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean. ... The bottom of the following image illustrates the land breeze that occurs at night. Recall that the land surface cools quicker than the water surface at night.
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
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.

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.

Answer:
''if we protect the nature, the nature will protect ourselves''.
Explanation:
Major lesson that is learned from the efforts to conserve green sea turtles in the Philippines is ''if we protect the nature, the nature will protect ourselves''. green sea turtles are very important for our environment because it provides nutrients in order to grow dune vegetation such as beach grasses, which help to prevent coastal erosion and maintain the structure of dunes present on the beach.

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 Electron Transport Chain and what happens in that stage of cellular respiration?
The electron transport chain (ETC) is the final step of cellular respiration and takes place in the mitochondrion.
The final step in cellular respiration is the electron transport chain. This is sometimes abbreviated as ETC. ETC needs oxygen, which means aerobic process. It occurs at the edges of the inner lining of mitochondria. These handles are called cristae.

7. Which molecule is light energy temporarily stored in before being used to make glucose?
Answer:
The Calvin cycle uses CO2 and the energy temporarily stored in ATP and NADPH to make the sugar glucose. Photosynthesis is a two stage process. As is depicted here, the energy from sunlight is needed to start photosynthesis. The initial stage is called the light reactions as they occur only in the presence of light
