what organ retains or releases body fluids, thereby regulating blood volume and blood pressure?
Answer:
excretion
Explanation:
waste
Answer: Kidneys
Explanation:
gene regulation can occur only during transcription and translation.
The statement described is false, gene regulation is a process that can occur at any time during the expression of a gene.
Gene regulation includes all those processes that affect the action of the final products of genes, that is, the regulation of the synthesis of macromolecules is called gene regulation or expression.
This regulation can be carried out at any stage of the synthesis or maturation of the macromolecules, and taking into account many variables it will be developed at the most appropriate point.One of the most important regulation points is carried out at the level of transcription, since this is the initial stage of transfer of genetic information, control is achieved at the beginning.Therefore, we can conclude that the pathway that leads from DNA to proteins is made up of multiple stages, and gene regulation can occur at any time during them.

Answer:
#3 Proteins
Explanation:
"There are four classes of macromolecules (polysaccharides or carbohydrates, triglycerides or lipids, polypeptides or proteins, and nucleic acids such as DNA & RNA). Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON)."
NEED IT ASAP!!! Which statement about the specific immune response is FALSE?
Clonal selection creates short-lived effector cells to destroy the specific antigen.
Clonal selection produces memory cells that are long-lived and can recognize the antigen in the future.
It takes about two weeks for memory cells to respond to an antigen.
The maximum response from effector cells takes about two weeks after the first time the body has been exposed to an antigen.
Memory cells divide to produce effector cells when they are exposed to their specific antigen.
Answer:
The answer is: Clonal selection produces memory cells that are long-lived and can recognize the antigen in the future.

If two organisms of different species share more similar DNA sequences with each other than with other species, we can conclude that ________.
If two organisms of different species share more similar DNA sequences with each other than with other species, we can conclude that these two species are very closely related.
Anatomy and embryology, molecular biology, biogeography, and fossils all provide evidence for large-scale evolution (macroevolution).Different species with comparable architecture may be homologous (shared by ancestry) or analogous (shared due to similar selective pressures).The similarity of life's molecules is evidence that it shared an ancestor. The connections between different species can be discovered by comparing DNA sequences.Biogeography, the study of the geographical distribution of organisms, provides information on the origin and evolution of potential species.The presence of extinct species in the past and evidence of long-term evolutionary changes are both shown by fossils.Learn more about the Evidences of evolution with the help of the given link:

The results suggest the optimum temperature for the enzyme is between which two values?
A 15 °C and 35 °C B
35 °C and 45 °C C
35 °C and 55 °C D
45 °C and 55°C
Answer:D
Explanation:
The optimum temperature for the enzyme is between 45 °C and 55°C. Therefore, option (D) is correct.
What is an optimum temperature for enzyme?Most enzymes perform best at a temperature of around 98.6 degrees Fahrenheit (37 degrees Celsius). Additionally, some enzymes function well both at low and high temperatures. For instance, while animals in desert climates have enzymes adapted to higher temperatures, those in the Arctic have them adapted to lower optimal temperatures.
The reaction rate will accelerate as more hydrogen peroxide is added to the mixture because more substrate molecules can interact with the enzyme and produce more product as a result. As you increase the amount of H2O2 in your reaction, more foam is generated in your cup as a result.

Describe how the diaphragm and the rib cage and lungs move during inhalation and
exhalation.
this is science pls help
Answer:
During inhalation, the diaphragm contracts and pulls downwards, the ribcage expands, allowing oxygen to be sucked in through negative pressure, which causes the lungs to inflate.
During exhalation, the diaphragm and ribcage relax, returning to their normal positions, allowing the oxygen out of the body, thus deflating the lungs.

d. The skull is flexible which allows the brain to grow
Answer:
c. The skull is hard which protects the brain from being injured
Explanation:
Answer:
The one that makes sense is C.) "The skull is hard which protects the brain from being injured." here's why:
Explanation:
The skull performs vital functions. Mainly, it supports and protects the head's soft tissues. The baby's skull is soft but as the bones developed, the bones of the skull form a tough, fibrous membrane and slowly fuse to form a single skull. The mandible is the only bone that separates from other parts of the skull. The skull or known as the cranium in the medical world is a bone structure of the head. It supports and protects the face and the brain. The adult skull has a total of 22 individual bones. They don’t move and united into a single unit. The skull performs vital functions. Mainly, it supports and protects the head’s soft tissues. The baby's skull is soft but as the bones developed, the bones of the skull form a tough, fibrous membrane and slowly fuse to form a single skull. The mandible is the only bone that separates from other parts of the skull. So, as our cranium grow it gets tough enough to protect the brain from injury!

Answer:
Community ecology!
Explanation:
I’m just did this assignment and got it right <3
A study is conducted to evaluate the effect of competition between foxes and coyotes for a limited food source. The level of ecology being studied is community ecology. The correct option is d.
What is community ecology?The ecosystem is the fundamental unit for maintaining life, although it extends beyond species living in a single location. The recycling of resources between organisms and their environments, between organic and inorganic forms, is essential to life.
Community ecology is the study of the structure and function of communities, which are assemblages of interacting populations of species living in a certain area or habitat.
A community in ecology is a group or association of populations of two or more different species that live in the same geographical area and at the same time, also known as a biogenesis.
Therefore, the correct option is d, community ecology.
