for the pupfish.
Answer:
hemeostasis
Explanation:
it makes sense because stress, response and hormones have nothing to do with the pupfish surviving. Homeostasis allows the pupfish's systems to remain stable and help them to survive these harsher conditions.

Which of the following is the non-living part of the cell?
A. Cell membrane
B. Cytoplasm
C. Mitochondrion
D. Cell wall
Explanation:
D. Cell wall is the non-living part of the cell
Answer:
It's Cell Wall.Explanation:
Cell Wall is the non-living part of the cell.Go outdoors and look for ten different plants. See if you can figure out which type of seed dispersal each plant uses, and make notes about each one. Some may have more than one method of dispersal. If you find a plant that you suspect disperses seeds in a way that you haven't studied, try to figure out how the plant does it. When you're finished, write your discoveries in a list with the name of the plant you observed (if you know it; otherwise, describe the plant).
Some you wouldn't see by stepping outside, but it gives you a general understanding of what you should be looking for.

The serous fluid within the pericardial cavity works to lubricate the membranes of the serous pericardium.
The pericardial cavityThe pericardial cavity is a space that is enclosed by the two layers of serous pericardium around the heart.
The pericardium is a thin, two-layered, fluid-filled sac that covers the outer surface of the heart. it is divided into 2 namely:
fibrous pericardium and serous pericardium.The serous fluid which is also called pericardial fluid helps to decrease friction between the pericardial layers. This is because, they lubricate the membranes of the serous pericardium.

The Gulf of Mexico dead zone is an area of hypoxic waters at the mouth of the Mississippi River. Its area varies in size, but can cover
up to 6,000 7,000 square miles. The zone occurs between the inner and mid-continental shelf in the northern Gulf of Mexico
beginning at the Mississippi River delta and extending westward to the upper Texas coast. Thousands of farms are located along the
Mississippi River and its tributaries and as water washes into the river after a heavy rain, it brings with it nutrients from fertilizers
added to farmland. These materials flow downriver and eventually enter the Gulf of Mexico, where they create conditions for a dead
zone: an area of low to no oxygen that results in the death of fish and other marine life. The Gulf of Mexico is a major source area for
the seafood industry. The Gulf supplies 72% of US harvested shrimp. 66% of harvested oysters, and 16% of commercial fish
Consequently, if the hypoxic zone continues or worsens, fishermen and coastal state economies will be greatly impacted. What can be
done to minimize the Gulf dead zone? Choose ALL that could apply
A)
B)
Control of animal wastes so that they are not allowed to enter into
waterways
Adjust the timing of fertilizer applications to limit runoff of excess
nutrients from farmland.
Monitor septic systems and sewage treatment facilities to reduce
discharge of nutrients to surface water and groundwater
Restrict land use in the areas surrounding the Mississippi delta to exclude
Industrial sites
Counter the effects of fertilizers on algal growth in the Gulf with the use
of chemical herbicides
D)
E
The things that should be done to minimize the Gulf dead zone include:
A. Control of animal wastes so that they are not allowed to enter into waterways.
B. Adjust the timing of fertilizer applications to limit runoff of excess nutrients from farmland.
E. Counter the effects of fertilizers on algal growth in the Gulf with the use of chemical herbicides.
It should be noted that it's important to manage nutrients efficiently in farmlands through the restoration of wetlands in order to capture nutrients and then reduce runoff.
In order to minimize the Gulf dead zone, there should be control of animal wastes so that they are not allowed to enter into waterways. Also, there should be an adjustment of the timing of fertilizer applications to limit runoff of excess nutrients from farmland.

What path does pollen need to travel for the plant to reproduce?.
Answer:
stigma
Explanation:
Pollination occurs when pollen grains from the anther land on a stigma. After pollen grains land on the stigma, a pollen tube grows from the pollen grain, through the style, and into the ovary. Sperm cells inside the pollen grain travel down the pollen tube and into the ovary which contains the ovules.
Answer:
The Stigma
Explanation:
This is the male reproductive cell, and then, when it travels through the Stigma, then, it goes on the top of the flower, then, a bee carries it to another plant's female reproductive cell, then the cells go into the embryo and create a plant's seed.

A condition known as varicose veins is due to leaky venous valves and causes blood to accumulate in veins. Why are valves found in veins, especially those in the lower extremities
Varicose veins are a form of chronic venous insufficiency, or a defect in the veins that prevents them from pumping blood properly.
What are venous valves?These consist of two elastic flaps of tissue that alternately open and close allowing blood to flow through the valve to another vein.
These work in conjunction with the musculoskeletal system, the muscles are constantly tensing and releasing, a pattern that causes the valves to open and close as needed.
Many veins are found, especially in the lower extremities, because they have valves that act in only one direction, a tightening of the muscles results in an opening of the valves, while a relaxation of the muscles results in the closing of the valves.
Therefore, we can conclude that one of the main functions of the venous valves is to guarantee the adequate return of blood to the heart, if a return flow occurs, the blood can begin to accumulate in the veins, potentially damaging them.
