Refer to Animation: Filtration, Reabsorption, Secretion. Cells of the excretory tubule _________water by osmosis, from which we can conclude that the solute concentration in these cells must be _________ than in the filtrate.
Answer:
Remove and lower.
Explanation:
Cells of the excretory tubule remove water by osmosis, from which we can conclude that the solute concentration in these cells must be lower than in the filtrate. The excretory tubule remove excess amount of water from the cell through semi permeable membrane of the cell while on the other hand, the solute concentration in the cell is lower as compared to filtrate so that's why it can't diffuse from the cell by the process of osmosis.
Which of the following is a process used by animals that produces carbon dioxide as a by-product?
Combustion
Diffusion
Photosynthesis
Respiration
Answer:
Respiration
Explanation:
Respiration is an exergonic process that involves the exchange of environmental oxygen and body carbon dioxide and the oxidation of glucose inside the mitochondria to produce energy which is partly stored in the ATP molecules as biologically useful energy.
Answer:
D
Explanation:
A secretion responsible for the development of a deep voice and facial hair is synthesized by
1.) Structure F
2.) Structure B
3.) Structure C
4.) Structure G
The development of a deep voice is due to structure C.
What is the thyroid gland?The thyroid gland is the gland that is responsible for deep voice. The gland is found at the anterior of the neck just around the Adam's apple. Over-secretion of the thyroid gland leads to a very deep voice.
From the structure shown, the development of a deep voice is due to endocrine secretion of a hormone from structure C.

plsssss help me with this .Evidence for evolution from living organisms comes from comparisons of their DNA, similar bone structures, and embryo similarities. Pick one piece of evidence and describe how supports the theory of evolution. piece of evidence and describe how supports the theory of evolution are comparisons of their DNA, similar bone structures, and embryo similarities.
Answer:
I pick embryo similarities.
Explanation:
Vertebrates have a resemblance of their embryos. Such as birds, amphibians, fish, reptiles and mammals. Though there's resemblance but it doesn't form the same organism since there's evolution which might be due to geographic and ecological isolations.
Example, Amphibian embryo resemble with fish embryo.
A blood specimen X is tested with blood group A serum and with B serum, both of which it agglutinate. To which blood group does X belong?
Answer: The blood group X belongs to is blood group AB.
Explanation:
Blood group typing is a process used in blood group serology to safely receive or donate blood during transfusion procedures. Blood groups found in human being can be put into four distinct groups, A, B, AB, and O, according to the antigens and antibodies that are found in the blood. Antigens are found on the surface of the red blood cells, while antibodies are found in plasma.
--> Blood group A: They possess A antigen on their red blood cells and antibody B in the serum
--> Blood group B: They possess B antigens on their red blood cells and antibody A in the serum.
--> Blood group AB: They possess both antigen A and B on their red cells with NEITHER antibody A nor B.
--> Blood group O: They possess neither antigen A nor B on their reb cells but has BOTH antibodies A and B.
In blood typing, we can identify our blood group by mixing a drop of blood with serum containing:
--> Anti- A antibody and
--> Anti- B antibody.
The clumping of red blood cells is called agglutination. The anti - A serum will cause the blood containing red blood cells with antigen A to clump while the anti- B serum would cause blood containing red cells with antigen B to clump. Therefore, specimen X is Blood group AB as the blood group contains both antigen A and B which clumps when added both A and B serum antibody.
Why do we always consider the Economic Threshold Level (ETL) in farming? What
advice you can give to the farmer about the control of insect pests considering
climate change?___________________________________________________________________________________________________________
Answer: Climate Change will always bring Pests/insects
Explanation: Pests and Insects migrate to better climate balanced areas when the climate in their habitat has changed and it's best to maintain crops from pests and insects but to be honest they will always come.

Are there any parts of the human body that get oxygen directly from the air and not from the blood?
Answer:
Yes. Upper-layer skin cells and the cells in the front surface of the eyes get a significant amount of oxygen directly from the air rather than from the blood. Human bodies have a huge demand for oxygen. As a result, the oxygen that is able to passively diffuse into the body directly from the air is not nearly enough to run the whole body.
Explanation:
How does an increase in the human population affect ecosystems?
