Answer:
Humans and marine organisms use sound finding depth of the ocean and objects.
Explanation:
Humans and marine organisms use sound for some underwater tasks such as finding depth of the ocean and objects. Human use sonar which is a device used to explore the ocean and animals use echolocation to find food and identify objects that comes in their way. Sonar is present in submarine uses sound waves to detect objects that comes in their way so both humans and marine organisms use sounds.
What would happen to Earth's climate if we had no moon, and why?
Answer:
The tilt creates what we know as seasons and changing weather. Without the pull of the moon, this tilt would change.
Explanation:
Either the tilt would become extreme, leading to extreme and severe seasons, or the tilt would decrease, and we would see almost no seasons at all. The moon influences life as we know it on Earth.
Answer: Because It is the pull of the Moon's gravity on the Earth that holds our planet in place. Without the Moon stabilising our tilt, it is possible that the Earth's tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).

with
ftri
Answer:
Due to stomata.
Explanation:
Transpiration occurs mainly through leaves because of the presence of stomata n the lower side of the leaves. Transpiration refers to the loss of water from the body of plants so leaves has small pores which is used by the plant to regulate internal temperature. Sunken stomata lower the rate of transpiration because it is not directly exposed to the surface which protects the escaping water vapor due to air.

In one of these systems, the prey are very large animals and the predators are verysmall animals, such as elephants and mosquitoes. Thus it takes many predators toeat one prey, but each prey eaten is a tremendous benefit for the predator population.The other system has very large predators and very small prey. Determine whichsystem is which and provide a justification for your answer.
Answer:
Due to its size and feeding requirement.
Explanation:
In the forest ecosystem, many lions feeds on one deer or buffalo because the food is in large amount and this food is enough to fulfill the requirements of that lions so we can say that many predators eats one prey while on the other hand, there are some predators that feeds on many prey at one because they are small in size and one prey did not fulfill their requirement so that's why the predator feeds on many preys. Fox feeds on many mice is the example of one predators feed on many prey.
What is the optimal pH that this enzyme functions at? And What is the optimal temperature that this enzyme functions at?
Answer:
Optimum Temperature is 35°C
Optimum PH is 7.0.
Explanation:
The optimum temp of enzymes is 20-35°c. They become inactivated at very low temperature and denatured (destroyed) at very high temp i.e. greater than 45°C. Low molecular weight enzymes are comparatively more heat stable.
The optimum pH of most enzymes is pH 7.0 (neutral pH).
A cluster of cases of legionellosis have occurred in your neighborhood. People with the illness have cough, fever, shortness of breath, chest pain and sometimes diarrhea. The illness is caused by the bacterium Legionella pneumophila, a facultative intracellular parasite that survives in certain ameba. The organism has an absolute requirement for L-cysteine. Typically, the organism is grown on buffered charcoal yeast extract (BCYE) agar. In some labs, samples containing suspected L. pneumophila are cultured on traditional BCYE medium as well as BCYE medium lacking L-cysteine. How would L. pneumohila be identified in this situation
Answer:
The correct answer is - comparing the presence of an essential component of the L. pneumophila that is cysteine.
Explanation:
As we know that L-cysteine is essential for the organism L. pneumophila to grow its colonies. The identification is easy in this situation by comparing the two cultured on the traditional BCYE medium and BCYE medicum without L-cysteine.
Colonies that grow on traditional BYCE medium are likely L. pneumophila as they required L-cysteine but not on BYCE medium lacking cysteine.
why is reproductive isolation insufficient to define a species?
A. This definition overlooks artificial preproduction, such as in zoos
B. Reproductive isolation doesn't take outgroups into account
C. This definition excludes organisms that reproduce asexually
D. Reproductive isolation can be accomplished in a variety of ways
The correct option is (c) This definition excludes organisms that reproduce asexually.
Asexual reproduction is also possible in bacteria, yeast, fungi, plants, and other organisms. Most frequently, yeast proliferate by budding. Plants and fungi both use spores for asexual reproduction. Additionally, plants are capable of reproducing asexually by vegetative propagation.Numerous eukaryotic creatures, such as plants, animals, and fungus, are also capable of asexual reproduction. Parthenogenesis, the most prevalent type of asexual reproduction in vertebrates, is frequently employed as an alternative to sexual reproduction when sexual reproduction isn't an option.What are the 4 types of asexual reproduction?Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.

What is a mold? in fossils
In a separate study, 68 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Sonora, Mexico. The other three were in Chihuahua, Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three Chihuahua locations were slightly darker than the dark-colored mice from the Sonora population. The entire Mc1r gene was sequenced in all 68 of the mice collected. The mutations responsible for the dark fur color in the Sonora mice were absent from the three different populations of Chihuahua mice. No Mc1r mutations were associated with dark fur color in the Chihuahua populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases.

How does this study support the concept that natural selection is not random?
Answer:
The study supports the concept that natural selection is not random because in different areas with the same or very similar environmental characteristics, the same phenotype was produced by different types of mutations.
Explanation:
All of the sampled animals are inhabiting dark substrate. Probably animals needed to camouflage to survive. Natural selection must have driven them to produce dark color, similar to the substrate color. So animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. The environmental condition is favoring the same phenotype.
The first stage of the cell cycle during which the cell matures and prepares to divide and copies
its DNA; The stage the cell stays in the most?
The cell multiplies and creates a copy of its DNA during interphase. In the mitotic (M) phase, the cell divides into two new cells by dividing its cytoplasm and DNA into two sets.
What is the main role of interphase stage of cell cycle?A cell consumes the bulk of its time in what is known as interphase, where it creates, duplicates its chromosomes, and acquires available to split. The cell then moves interphase, goes direct mitosis, and completes dividing.
The cell multiplies and the nuclear DNA is duplicated during interphase. The mitotic phase immediately follows interphase.
Chromosomes that have been duplicated are separated and distributed across daughter nuclei during the mitotic phase. Usually, the cytoplasm is divided as well, producing two daughter cells.
Therefore, The first stage and the stage the cell stays in most is Interphase.

1.) A person walks 12.5 km in 1.9 h. What is the person's
average velocity in km/h and m/s?
Answer:
1. 6.56 km/hr
2. 1.83 m/s
Explanation:
The average velocity/speed can be calculated using the formula;
Average speed/velocity = distance/time
According to the information provided in the question, distance = 12.5km, time = 1.9h
Average velocity in km/hr = 12.5/1.9
= 6.578
= 6.56km/hr
However, in order to calculate the average speed in m/s, we have to convert distance in km to m, and time in hour to seconds.
1km = 1000m
12.5km = 12.5 × 1000
= 12500m
1 hour = 3600seconds
1.9hours = 1.9 × 3600
= 6840seconds
Average velocity = 12500/6840
= 1.827
= 1.83m/s
