Answer:
The correct answer is - to provide a slightly cooler temperature.
Explanation:
The scrotum is a sac pf skin and superficial fascia that contains testes present outside of abdomopelvic cavity or ventral body cavity, hanging provides a slightly cooler temperature f at roots of penis.
Testes produces sperm, for the sperms it require to be cooler temperature than the body cavity or optimal sperm production will be hampered. Scrotum gives 3 degree temperature less than the body cavity.
Thus, the correct answer is : to provide a slightly cooler temperature.
Name and define the two basic kinds of reproduction
Answer:

When scientists carefully measure the lichens and agree on their average thickness and how often they appear, which parts of the scientific cycle are the scientists using
Answer:
Answer: process and facts, because they are using a systematic method to measure and then record data
Explanation:
During a study of lichens and air quality in part of China, scientists measure the thickness of lichens and estimate how many rocks and trees are covered with lichens in one town. The scientists are following the scientific cycle of observing while using a systematic process, establishing facts, explaining facts, and then returning to the systematic process to collect more facts.
When scientists carefully measure the lichens and agree on their average thickness and how often they appear, which parts of the scientific cycle are the scientists using?
Answer: process and facts, because they are using a systematic method to measure and then record data
The parts of the scientific cycle are the scientists using process and facts, because they are using a systematic method to measure and then record data. The correct option is A.
What is scientific cycle?Simply put, when scientists discuss periods, they are referring to sequences of events that recur themselves. Some cycles are extremely simple.
Scientific theories are generally born and die as a result of what is known as the scientific process.
This is a general cycle in which a pattern in some phenomena is identified, a general hypothesis is formed, new phenomena are predicted based on this supposition, and the predictions are tested by experiment.
The research and development cycle is made up of five iterative activities: problem analysis, underpinning, design, integration, and evaluation.
Scientists use procedure and facts as part of the scientific cycle even though they use a systematic method to gather and then record data.
Thus, the correct option is A.

Some fungal species can kill herbivores while feeding off of sugars from its plant host. What type of relationship does this fungus have with its host?
Answer:
parasitism
Explanation:
In evolutionary ecology, parasitism is a symbiotic relationship between species, where one organism, the parasite, lives on or in another organism, the host, causing it some harm, and is adapted structurally to this way of life.
The type of relationship this fungus have with its host should be parasitism and the same should be considered for the given situation.
What is parasitism?Parasitism refer to the close relationship that lies between the species in which the one organism should be live or inside the other organism as per the life, the host should lead some kind of harm and adopted the structure.
Therefore, we can conclude that The type of relationship where fungus involve with its host likely be parasitism.

The definition including its given subject is provided in the subsection below on clarification.
Explanation:
Slightly earlier astronomers didn't rely on technology-they only stayed up throughout the night in something like a profession and glanced up to take a track of what they would have seen. They require innovation if they wish to do it more than anything. Today scientists really would like to grasp extraordinarily distant or very small objects so they need many more technologies, such as analyzing frequencies that only the human eye couldn’t detect.A solution that is hypotonic to a cell has A. fewer solutes than the cell.

How can a female inherit red-green color blindness?(1 point) Her mother is a carrier, and her father has the condition. Her mother is not a carrier, and her father has the condition. Females cannot inherit red-green color blindness. Her mother is a carrier, and her father does not have the condition.
Answer:
The correct answer is - Her mother is a carrier, and her father has the condition.
Explanation:
Colorblindness is a sex linked recessive disease that is passed from the parent to the offspring through X chromosome that have recessive gene of the disease. It is rare in the females as the very low chances of the females to inherit two copies of disease gene allele. But as only one allele is present in males of X chromosome and if there is disease copy he will be color blind.
To get a colorblind female the girl child must get two copies of these allele that has recessive X chromosome one from her carrier mother and other from her conditioned father. Check image for punnet.
Thus, the correct answer is - Her mother is a carrier, and her father has the condition.

For a plant, sunlight is an
a. internal stimulus
b. external stimulus
C.
homeostasis
d. reproduction
Answer:
Explanation:
homeostasis
For a plant sunlight is an example of ; ( C ) homeostasis
Plants require the light to carryout photosynthesis for proper growth and production of its food therefore insufficient sunlight will affect the growth and development of a plant. also some plants grow towards a light source ( phototropism ). to maintain its internal system.
Since the sunlight is not found within the plant but it has a direct effect on the growth and development of the plant, it is an example of a homeostasis while reproduction takes place within the plants
Hence we can conclude that for a plant sunlight is an example of ; ( C ) homeostasis

Is a vesicle found in an animal or plant cell. or both?
Answer:
Both, although they're less common in plant cells.
Both plant and animal cell have vesicle.
what are the difference between animal cell and plant cell?Plant cell have cell wall and other cell organelles while animal cell do not have cell wall but other organelles are present, has fixed-size and shape due to presence of rigid cell wall while animal cell have irregular size and shape.
Plant cell has rigid cell wall and plasma membrane while animal cell has flexible and thin plasma membrane for this reason animal cell can change their shape.
In plant cell Plastids like chloroplast, chromoplast, leucoplast and nucleus is present on one side where as plastid are absent in animal cell and nucleus is present in the central region in case of animal cell.
Plant cell can do photosynthesis and make their own food, so they are phototrophic where as animal cell do not have cell wall.
