Answer:
The dolphins population may diminish a little.
Explanation:
Crabs are one of the many things dolphins eat, and, as the prompt suggest, they cannot live in temperature greater than 60 degrees F. If climate change makes the temperature 62 degrees F, the crab population will all die. However, note that dolphins do not only eat crabs, as they have other food sources. However, crabs are a major population, so we can see a disruption in the food web, with there being less dolphins than usual.

How do the data that Samantha obtained help explain the way that the body maintains homeostasis during exercise? Include the activities of at least three body systems in your explanation.
Answer:
the way that the body maintains homeostasis during exercise is the removal waste product such as carbon dioxide gas which is produced during cellular respiration.
Explanation:
During exercise, the body needs more oxygen and nutrients. For this purpose, energy is released in the process of cellular respiration. The product of cellular respiration the generation of energy in the form of ATP and carbon dioxide gas. ATP is used by the body while carbon dioxide is removed from the body during breathing. During exercise, the glucose is provided by the digestive system to the mitochondria of the cell and the waste product is removed through respiratory system of the body while the circulatory system sends energy molecules where it is needed in the body and carbon-dioxide to respiratory system for removal.
Why can the geologic time scale change?
Absolute time measurements can be used to calibrate the relative time scale, producing an integrated geologic or "geochronologic" time scale. The overall duration and relative length of these large geologic intervals is unlikely to change much, but the precise numbers may "wiggle" a bit as a result of new data.

What are the two reasons for the change in the population of giraffes?
Answer:
Two reasons are that the grasses they ate disappeared which caused some to die, but some lived and ate from trees and reproduction and such happened.

Red squirrels and gray squirrels have been the native species on an island for many years. A few years ago, black squirrels entered this island. The black squirrel is an invasive species. Invasive species aren't native to the ecosystem. They move into an ecosystem because of natural changes or human intervention. Red squirrels and black squirrels have identical food requirements, but gray squirrels have a different diet. What three effects will these events have on the island's squirrel population?
Answer:
1. There will be direct predation of species.
2. There will be competition for limited resources like breeding sites, prey.
3. Transmission of diseases or they can cause danger to the native species.
Explanation:
Invasive species are species of organisms that are not natural to an ecosystem and move to an ecosystem because of natural changes and human intervention. Islands are prone to the invasion of invasive species because they don't have predators and there is no competition that control populations in their ecosystem. The invasion of black squirrels will lead to competition for limited resources like breeding sites or prey, the black squirrels will begin to predate other squirrels because they have different nutrients requirements and they can transmit diseases to other squirrels if they are carrier.

Keith and Marsha's only child to have a carrier genotype, Jeff, did marry. Cedric remained single due to poor health, and Nita swore off marriage after several bad relationships. Jeff and his wife Adrienne had four children, Angela, Keith, Joyce, and Denise. Although the parents were not expecting it to happen, their only son and their second born girl were born with sickle cell disease. Post- pedigree questions: If you were Ketih and Marsha's genetic counselor, what would you tell them? _____________________________________________________________________________________ Which of the Jackson's grandchildren are definitely carriers? _____________________________________________________________________________________ What is Adrienne's genotype? ________________________________
Answer:
Answer to Question 1:
Sickle cell anemia is a recessive disorder. The fact that one of their children is a carrier means that either of Keith and Marsha is a carrier ot it might be that both of them are carriers of the disease.
Answer to Question 2:
The other two kids of Jeff and Adrienne who don't have the genetic disease are still carriers of sickle cell anemia.
Answer to Question 3:
Adrienne is a carrier of the sickle cell anemia disease as well, just like Jeff.

What are the functions of cell?Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
Cells provide structure and function for all living things, from microorganisms to humans. Scientists consider them the smallest form of life.

Which characteristic makes fungi similar to plants?
Answer:
They are both non-mobile and eukaryotic.
Explanation:
Plants and fungi both remain stationary. They do not move around for their food. Another similarity is that they both are made up of eukaryotic cells, meaning they contain a nucleus.
Answer:
While both are eukaryotic (both have nucleus) and don't move, plants are autotrophic, making their own energy - and have cell walls made of cellulose, but fungi are heterotrophic, taking in food for energy (so they eat dead and decaying food), and have cell walls.
