Answer:
Oxygen molecules
Explanation:
Plants, during the process of photosynthesis, give off oxygen molecules as a by-product of the process.
Plants, through the process of photosynthesis, use the energy gotten from sunlight to produce glucose from carbon dioxide and water molecules, and in the process, oxygen molecules are released into the atmosphere as by-product.
Therefore, the label A in the diagram represents molecules of water that is given off by plants.

Answers
Answer:
Photosynthesis is the process by which plants and other things make food.It is an endothermic (takes in heat) process.Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy.
Explanation:(what happens in this process)
-Sunlight energy is converted into chemical energy by using chlorophyll.Gives plants their green color to the plants.
- Chlorophyll absorbs red and blue light and uses the energy to convert water and carbon dioxide into glucose.
- Plants convert sugar and energy from water, air and sunlight into energy to grow
- formula for photosynthesis : 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy
-formation of carbohydrates from carbon dioxide and a source of hydrogen in the chlorophyll-containing cells (as of green plants) exposed to light.
- Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis .

If a fat source is counted towards an individual's discretionary calories, what does this mean?
a. This fat source should account for 30% of the daily fat intake.
b. This fat source supplies essential fatty acids.
c. This fat source can be consumed in great quantity with no adverse health effects.
d. This fat source is high in saturated fat and its intake should be limited.
e. This fat source should be a consistent part of a person's diet.
Answers
The correct answer is D. This fat source is high in saturated fat and its intake should be limited.
Explanation:
In nutrition, the term "discretionary calories" refers to extra calories that are not part of nutritional requirements but can be consumed sporadically. In the case of fat sources, this includes foods such as cheese, butter, or fried foods that contain high levels of fat, especially saturated fat, which contributes to heart disease and other conditions. Due to this, these types of food are consumed as part of "discretionary calories", which means their intake is not essential and should be limited. Thus, if a fat source is counted towards discretionary calories it means it should not be consumed daily but its intake should be limited because it contains saturated fat (Option D).

Answers
Answer:
The correct answer is - eliminates all lymphocytes that have been built that would bind and kill healthy, unaffected body cells.
Explanation:
Self-testing in the immune system is a very important step as it helps in analyzing if the immune cells or lymphocytes. To fight against the intruders, the immune system should initially recognize them. That is, the immune system must have the option to recognize what is nonself (remote) based on what is self. The immune system can make this identification since all cells have distinguishing recognition molecules (antigens) on their surface.
Self-test helps in identifying and eliminate in all lymphocytes that have built and attack the healthy cells and killing them.

As a result, the offspring ratios are not what Mendel would have predicted. Which statement about these meiotic drive genes is true
Answers
The given question is incomplete as the statements are not give, however, the the answer is given on the general knowledge about the question:
Answer:
The correct answer would be - They violate the law of equal segregation.
Explanation:
According the first law of Mendel, the law of segregation that says that during gamete formation, the two alleles, present at a gene locus segregate from one another and each gamete has 50% of containing any of two allele.
In meiotic drive genes, the alleles present are if present in a heterozygous state, are able to become incorporated into much more than 50 percent of the gametes which is against the law of segregation.
The correct answer would be - They violate the law of equal segregation.
Based on your understanding of the process of photosynthesis, what are the strengths and weaknesses of this model?
Answers
Answer:
photosynthesis is the process of making food by plant in presence of sunlight and chlorophyll in necessary condition is called photosynthesis .
i think its strength are,
1. it converts the light energy, co2and water inthe form of glucose.
2. it manufactures oxygen during this process.
some weakness are,
1. if there is no sunlight then this process cannot be performed.
2. it may take a long time to do this process.
hope it helps uh..
Answer:
The model’s strength is that it clearly shows that the process is quite complicated and that it takes place in different parts of the chloroplasts. It also shows most of the major molecules produced. But it doesn’t show the major steps of the Calvin cycle, so that’s a weakness of the model. It also doesn’t clearly show the process of the electron transport chain.

Water high heat capacity.
Explanation:
Water high heat capacity is the ability of the water to be able to absorb high heat energy and this is brought about hydrogen bonding among water molecules.
Water high heat capacity causes it to moderate the climate around lakes by absorbing heat in the summer and slowly releasing hear in the winter. This high heat capacity of water that moderate climate around lakes is as a results from both the higher specific heat of water and heat mixing throughout a greater depth over the lakes.

The size of the stem increases in the width due to the ........... meristem.
Answers
Answer:
Intercalary
Explanation:
There are three types of meristems : apical, lateral and intercalary.
These are found at different parts of the plant, but their ultimate job is to multiply and so increase the length of the plant.
The length of the stem is determined by the apical meristem, which is found at the tip of the plant.Of this meristem múltiples, the plant grows taller.
The root of the meristem is determined by the lateral meristem, which is found at the bottom of the plant, near the roots.
The thickness of the plant is determined by the intercalary meristem, which is found at the centre of the plant, and when they multiple, the plant increases in width.
Hope this helps.
Good Luck.
Which is false?
A) fatty acids can enter Krebs cycle through a process called beta-oxidation
B) ATP can inhibit the enzyme phosphofructokinase
C) Too much NADH can inhibit pyruvate decarboxylase
D) DNA is often broken down to enter Krebs Cycle
Answers
Answer:
D) DNA is often broken down to enter Krebs Cycle
Explanation:
A) is true. Beta-oxidation is a process whereby fatty acids serves as precursor for cellular respiration. It is the catabolism (metabolic breakdown) of fatty acids into ACETYL coA, NADH and FADH2 molecules, which enters the Kreb's cycle to continue the process of cellular respiration.
B) is true. Phosphofructokinase is an enzyme that catalyses the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate in glycolysis. However, phosphofructokinase enzyme has been shown to be allosterically inhibited by ATP and citrate by reducing its ability to bind to its substrate (fructose-6-phosphate).
C) is true. Pyruvate dehydrogenase is a complex of enzymes that catalyzes the oxidation of pyruvate into ACETYL coA. This oxidation of pyruvate produces C02, acetyl coA and NADH molecules. Hence, the Pyruvate dehydrogenase complex can be inhibited by its own product (NADH) if produced in excessive amount.
D) is false because Deoxyribose nucleic acid (DNA) is never broken down to enter the Kreb's cycle. DNA is a nucleic acid strictly for the storage of genetic information in a cell. It has no business with cellular respiration.

Dependent variable: the effect that depends on the independent variable.
For example, an experiment measures how light (independent variable) affects plant growth (dependent variable). Every other component of plant growth is kept the same to isolate the effect the independent variable has on the dependent variable.
So, the independent variable is CHANGED while the dependent variable is OBSERVED

explain the structure of nephrons
Answers
Structure of nephron : The filtration units in the kidney are called nephrons. Each kidney has a large number of nephrons which are packed closed together. Nephrons consist of a cup shaped Structure called Bowman's capsule in which a cluster of very thin walled blood capillaries form glomerulis . This cup shaped structure is followed by long tubular structure which is convoluted , twisted and finally leads to the collecting duct.
Functions of nephron : : Nephrons help in filtering nitrogenous waste from the blood. The blood entering the glomerulus contains waste which are filtered in the Bowman's capsule. The filtrate formed may contain some useful substances such as glucose, amino acids, salts and a major amount of water. These are selectively reabsorbed as the urine flows along the tube, The amount of water reabosrbed depends on how much excess water is there in the body andhow much dissolved waste there is to be excreted .
* For structure of nephron * refer to attachment !

Answers
Answer:
1) they share a common ancestor
2) the Archaeopteryx came after dinosaurs but before birds
Explanation:
Birds, dinosaurs and Archaeopteryx evolved from a common ancestor so we can say that they share a common ancestor. With the passage of time, changes occurs in the structure of an organism and a new species is formed. Same events occurs with ancestor of birds, dinosaurs and Archaeopteryx. Archaeopteryx is a transitional fossil that comes after the dinosaurs and before the birds. Archaeopteryx is also known as the first on the earth. With the passage of time some dinosaurs bears wing and then converted into birds.

The order of arrangement is as follows
Lichen →Grass → Moss → bushes → Flowers → Pollinators → Trees → Primary consumers → Secondary consumers → Tertiary consumers
Explanation:
The type of succession that results in a successful ecosystem where initial soil condition is a volcanic island devoid of life any life form and without a soil formation is that of primary succession and involves the gradual ecosystem growth in a long time duration
Organic activity in primary succession is started by pioneer organic species which develop a community of interacting organisms from their biological activities resulting in the arrival of new species and the continuing development simple initial community into a successful complex ecosystem.
