I really need help please
Answer:
There should probably be some proof in the information above, but the mass would be lost through excretion, respiration, sweating, and movement
Explanation:
Answer:
Ok, in the diagram it looks like there are arrows pointing to its mouth and its rear end right so my best guess would be that the rabbit eats the food, some of the mass is turned into energy and the rest of it goes out the rear end. I'm assuming they want you to explain how mass is turned into energy and travels throughout the body.

What is the name given to the process by which a parent cell becomes two identical daughter cells?(1 point)
A. meiosis
B. differentiation
C. senescence
D. mitosis
Answer:
D. mitosis
Explanation:
Mitosis is the process whereby the parent cell divides into two daughter cells that are identical.
Mitosis is the process by which a parent cell becomes two identical daughter cells. So, the correct option is (D)
What is mitosis ?Mitosis is the process in which cell duplication, or reproduction takes place. Wherein one parent cell gives rise to two genetically identical daughter cells. Mitosis is the duplication and distribution of chromosomes which carries the genetic information.
It is an important process in single celled eukaryotes as it is the mode of asexual reproduction. The main function of Mitosis is to produce more cells.
Life starts with single cell in multicellular organism which is formed from two gametes. Mitosis takes place one cell is divided into two cells as this single celled multicellular organism only carries genetic information in the form of DNA but not enough cells. These two cells further divide mitotically into four cells, then into 8 , then 16 and then 32.
It is essential to life because it give rise to new cells for growth and replacement of dead cells. It may take few minutes or some hours, depending on the type of cells. It depends on time, temperature and chemicals.
Thus, mitosis is the process by which a parent cell becomes two identical daughter cells. So, the correct option is (D).

during which phase of mitosis are the spindle fibres formed around the sister chromatids?
Answer:
Metaphase
Explanation:
In prophase, spindle fibers start emerging from the centrosomes. In metaphase, the spindle fibers attach to the sister chromatids.
How does your body respond to a decrease in blood glucose
Answer:
When blood sugar drops too low, the level of insulin declines and and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels back up to normal

why is the concentration of oxygen in the body cells lower than the concentration of oxygen in the alveolus?
A. Alveolus can produce oxygen.
B. The exchange of gases occur in the alveolus.
C. Oxygen is used up for respiration I the body cells.
S. Oxygen diffuses out from the body cells.
Answer:
i think the answer should be b.
the alveolus is the site of exchange of gases (carbon dioxide and oxygen) between the body cells and the alveolar air. diffusion requires a concentration gradient, which basically means that there has to be a difference in concentration of the substance (in this case it's oxygen) between the 2 areas (in this case it's the body cells and the alveolar air) hence, there is more oxygen in the alveolar air than the body cells (this difference in concentration is what allows diffusion of oxygen from a region of HIGHER to LOWER concentration!) this allows oxygen to diffuse from alveolus to body cells, giving your body the oxygen it needs!
btw keep in mind that i am by no means an expert in biology (because im still a student), but b is the most logical answer to me. good luck!

how is the energy in food used in our body
Answer:
The human body uses the energy released by respiration for a wide range of purposes: about 20% of the energy is used for brain metabolism, and much of the rest is used for the basal metabolic requirements of other organs and tissues.

O Build-up of garbage in freshwater
O Quick drop in dissolved oxygen
O Decrease in algae colonies
O Sudden hypoxic waters
HELP PLZ
Answer:
I believe it would be B.) Quick drop in dissolved oxygen
Quick drop in dissolved oxygen is a possible consequence of solid pollutants in a lake or river.
What is Biological Oxygen Demand?
Biochemical oxygen demand (BOD) is the amount of oxygen consumed by bacteria and other microorganisms while they decompose organic matter under aerobic conditions.
Solid pollutants in freshwater bodies like river and lake generally corresponds to organic wastes such as leaves, flowers and clothes which lead to increase in number of microorganisms in these water that further results in increase of BOD.
Drastic increase in microorganisms lead to drop in amount of dissolved oxygen in water, thus the possible consequence of solid pollutants in a lake or river is quick drop in dissolved oxygen.

what is Krebs cycle?
Is Krebs cycle also known as cellular respiration?
Explanation:
The tricarboxylic acid (TCA) cycle, also known as the Krebs or citric acid cycle, is the main source of energy for cells and an important part of aerobic respiration. It takes place in the mitochondria, using up oxygen and producing carbon dioxide and water as waste products, and ADP is converted to energy-rich ATP.
No Krebs cycle is not known as cellular respiration

Answer these questions about making a yogurt.
1) why is the milk pasteurized at the start of the process?
2) Why is the mixture of milk and bacteria incubated at 45 °C?
3) what causes the milk to thicken?
4) why does fermentation eventually stop?
5) Explain how making yogurt is a way of preserving the nutrients from milk.
It should be noted that milk is pasteurized at the start of the process in order to kill bacteria.
The mixture of milk and bacteria is incubated at 45 °C to kill the bacteria.The drop in pH causes milk to thicken. Fermentation is stopped when the alcohol concentration rises to a point where it kills the yeast cells.Lastly, making yogurt is a way of preserving the nutrients from milk as the bacteria ferment the milk thereby turning the lactose sugars to lactic acids.

which is the primary advantage to sexual reproduction over asexual reproduction?
Answer:
Sexual reproduction is typically advantageous over asexual reproduction because the environment is constantly changing. Sexual reproduction allows new combinations of genes to form. This greater genetic diversity increases the phenotypic variation: that is, it increases the physical variety of the organisms.

To test a new drug that has the potential of curing people of the common
cold a company asked human volunteers who were coughing and sneezing
to participate in a clinical study. The objective of the experiment was to test
whether the new drug could cure the volunteers in the experimental group of
the common cold. But instead of two groups, these volunteers were randomly
divided into three groups and treated as follows:
Group
Experimental
Group
Yes
Control
Group 1
NO
Control
Group 2
No
New ONS
Orange
Bedre
Yes
No
Yes
Yes
Which of the following is the best explanation of why a second control group
was included in this experiment?
O A To prove that the common cold cannot be cured
B. To provide the volunteers in the study with something to drink
O C. To help researchers conclude that results are related to the new
drug and not to the orange juice
O D. To confuse anyone who is trying to steal their new drug and sell it
as their own invention
Answer: C
Explanation: A good experiment does everything it can to eliminate confounding, or the influence of external sources on the data being measured. Orange juice could be a factor that plays a role in curing the symptoms, so provide a group with and without orange juice gives you the ability to show that the influence of orange juices didn’t have an effect on the cold, or did, but it gives you a baseline to show the effects of the medicine with and without orange juices.
