Due to lack of certain features, sea stars can't live in land environment.
Why can't sea stars live in terrestrial environments?Sea stars can not live in terrestrial environments because of the body structure which is fit for water not land environment. Every organism has special features that allows it to live and survive in that specific environment.
So we can conclude that due to lack of certain features, sea stars can't live in land environment.

Explanation:
Rock pocket mice are rodents found in the desert Southwest. They are typically light/tan, but a mutation in the population codes for a
darker fur color. The two fur colors are shown in the images here. The area where these mice live typically have a sand with a tan
background. However, there are areas of cooled lava from a volcanic eruption 10,000 years ago that deposited black rock. The mice
are found on the sand and on the rocks.
Researchers set traps to collect samples of mice from the rocks and the sand areas. An analysis of the data for the mice caught in
each of the areas would show which trend if natural selection were acting on the different phenotypes?
Answer:
B) Visual predators favored the tan mice on the dark rock and black mice on the light rock.
C) The black mice on the black rock camouflage better, allowing them to survive and reproduce.
E) There are more black mice in the dark environment and more tan mice in the light environment.
Explanation:
I just did it on USATestPrep
The correct option are :
The visual predator favored the tan mice on the dark rock. The black mice on the black rock can camouflage better. The more black mice under dark environments and more tan mice under light environments.What are rock pocket mice?The rock pocket mice are 19 specie of the pocket mice and they are found mainly in the rock out crops of the desert of the southwestern US and Mexico and medium-sized mice of 18 cms.
They have a breeding season that starts in fed to march. They are dark in color and can easily camouflage with the surroundings and this gives them an advantage over the light white mice.

Name two types of fluids
found
in female reproductive
Organs
Answer:
A female's internal reproductive organs are the vagina, uterus, fallopian tubes, and ovaries. The vagina is a muscular, hollow tube that extends from the vaginal opening to the uterus. Because it has muscular walls, the vagina can expand and contract.
Explanation:
Welcome!
Answer:
The oviduct and uterus provide the environments for the earliest stages of mammalian embryo development. However, little is known about the mechanisms that underlie the formation of oviduct and uterine fluids, or the extent to which the supply of nutrients via these reproductive tract tissues matches the nutrient requirements of early embryos. After reviewing our limited knowledge of these phenomena, a new experimental paradigm is proposed in which the epithelia lining the endosalpinx and endometrium are seen as the final components in a supply line that links maternal diet at one end and embryo uptake of nutrients at the other. When considered in this way, the oviduct and uterine epithelia become, for a few days, potentially the most critical maternal tissues in the establishment of a healthy pregnancy. In fulfilling this 'gatekeeper' role, female reproductive tract fluids have a key role in the 'developmental origins of health and disease' concept.

In a paternity case there is a child with type O blood, and the mother has type A. The first potential Father has type A blood as well and the second potential Father has type B blood. Would blood type be enough to tell us which man is the father? *
Answer:
Blood type information is not enough to tell us which man is the father. We need to know the exact genotype of individuals to know which father gave the child a recessive allele.

Which of these four solutions will dissolve the plastic wrapper fastest?
Water
Boiling water
Apple cider vinegar
Soda
Acetone
Answer:
Acetone
Explanation:
Answer: Acetone.
Explanation: Acetone molecules have a polar carbonyl group that allows them to ACCEPT hydrogen bonds from OTHER compounds. The slightly positive charge on each hydrogen can attract slightly negative oxygen atoms on other water molecules, forming hydrogen bonds. If acetone is added to water, acetone would completely dissolve.
What has been the experience of cats and dogs in space? Explain several different situations in which cats and dogs were involved with space travel. its astronomy
Answer:
Animals in space originally served to test the survivability of spaceflight, before human spaceflights were attempted. Later, other animals were flown to investigate various biological processes and the effects microgravity and space flight might have on them. Bioastronautics is an area of bioengineering research which spans the study and support of life in space.
Explanation:
Example 1: Albert II became the first monkey in space on June 4, 1949. He reached an altitude of 83 miles (134 km), but died on impact when the parachute failed. A previous monkey, Albert I, died when the V-2 rocket failed before reaching peak altitude. Two other monkeys, Albert III and IV, also died when their rockets failed.
Example 2:A mouse launched on Aug. 15, 1950, attained an altitude of 85 miles (137 km), but died when the rocket disintegrated due to parachute failure. Several other mice were launched during the 1950s.
Example 3 (and the most important example): Laika became the first living being to orbit the Earth on Sputnik 2, Nov. 3, 1957. She died several hours into the flight from stress and heat.

Explanation:
What are the answers to 10 and 11?
Answer:
The correct answer is -
10. 20 J
11. 29.31 %
Explanation:
According to the law of 10% energy transfer, the energy only transfers 10% energy from one tropic level to another and the rest 90% lost in the form of heat during the metabolic and excretion process.
So, 2000 J transfers only ten percent to the primary consumer that is 200 J and then ten percent of that transfers to long-tailed weasels that are 20 J.
11. The percentage efficiency -= energy after transfer*100/transfer before the transfer
= 350*100/1170 = 29.31%
