Explanation:
1) The net force is simply the sum of all given forces. Therefore,
net force = 2N in the upwards direction
(or North)
2) Net force equals 3N + 2N = 5N to the left
( or West)

Which sentences should she use in her explanation? Select all that apply.
A. An ecosystem cannot function without consumers.
B. Herbivores are food for carnivores and omnivores.
C. Consumers in an ecosystem may be herbivores or carnivores.
D. Most ecosystems have only one type of consumer.
E. The same types of consumers are found in different ecosystems.
Answers
Answer:
The answer is definitely A
A - An ecosystem cannot function without consumers because if there were sheep and foxes the sheep would keep reproducing with no one to keep their population low and would eventually eat all their food. An ecosystem needs to balance consumers, predators, and omnivores
B - Herbivores eat plants only, but usually the carnivores and omnivores eat them as their food and lower their population
C - Yes, consumers are species that consume another. They could be consuming plants or consuming another species
It’s not D or E
D - Ecosystems are made up of different types of species and they’re not made up of one consumer it’s a complex system where everything balances
E - Different ecosystems are made up of different species for example you won’t find fish in a land ecosystem and you won’t find wolves in an underwater ecosystem.

The structure of sperm cells as it relates to their function are:
The head: It helps carry the genetic information to the haploid nucleusThe acrosome: It helps the sperm enter the egg of the femaleThe middle piece: It is responsible for the release of energyThe tail: It helps the sperm to swimA sperm cell is the male sex cell which is responsible for reproduction as it fuses with the female gamete and forms a zygote through fertilization.
As a result of this, there are different processes which are required for fertilization to occur as the sperm cell has to move through the head and fertilize with the ovule to form a new cell, called zygote.

Insular biogeography or island biogeography is a field within biogeography that examines the factors that affect the species richness and diversification of isolated natural communities. The theory was originally developed to explain the pattern of the species–area relationship occurring in oceanic islands.
The reptile population decreases as arthropods decrease with their habitat
Migrating species are more likely to find larger habitats over smaller ones. Explanation: The concept of island biogeographical model establishes that larger islands and habitats will have a larger number of species than a smaller island. Larger islands have more tendency to attract new species.The species–area relation, whereby the number of species in a spatial unit increases with that unit’s area, well predates the MacArthur and Wilson theory of island biogeography, having been documented for about 150 years. Two general kinds of models for this relation have been proposed. The first has number of species predicted from an assumed species–abundance distribution and the total number of individuals of all species combined (assumed proportional to area). The second develops species–area relations from MacArthur and Wilson’s species-equilibrium approach.

W Within a forest ecosystem, there is a large amount of diversity among members of a warbler species. Of the following stages of meiosis illustrated for a typical cell, which contributes most to diversity among the warblers? Pay special attention to the chromatids.
Answers
Answer:
Explanation:
How a Forest Ecosystem Matures . Forest ecosystems tend to always be moving toward maturity or into what foresters call a climax forest. This maturing, also called forest succession, of the ecosystem increases diversity up to the point of old age where the system slowly collapses. One forestry example of this is the growth of trees and the entire system moving toward an old growth forest.
A Large amount of warbler species, crossing over between homologous chromosomes, is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.
There are different mechanisms involved in producing genetic variation among descendants, are-
Crossing-over between homologous chromosomes (prophase 1), The Random lining of homologous chromosomes (metaphase 1), Random fertilization
The Crossing-over events occur between two homologous chromosomes within the equatorial plane and make the daughter cells genetically different from the first one.
The Chiasma is the position where two homologous chromatids interchange genetic information, giving an area for brand spanking new genetic material or information to be provided to descendants.
After crossover, homologous chromosomes get separated again. In the attached image there are four different stages of meiosis.
Stage C is the one that contributes foremost to diversity. We can see that crossover has already occurred between homologous chromosomes and that they have already interchanged segments.
In the image, you will see the difference between chromosomes that have gone through the crossing over mechanism, and chromosomes that have not. The difference in color represents segments interchange and variation.
Therefore, that answer shows the contribution to diversity among the warblers.

On a scratch sheet of paper, complete the Punnett square of the cross between two heterozygous red-eyed flies (Rr). What color eyes will the offspring have?
Answers
Answer:
75% red, 25% other color (brown?)
Explanation:
A cross between two heterozygous red eye flies (Rr x Rr)
R r
R RR Rr
r Rr rr
The possible genotypes are RR, Rr, and rr. There are two possibilities of Rr.
Since the heterozygotes have red eyes, the red eye allele must be dominant. Therefore, RR and Rr genotypes will all have red eyes. That means 3/4 (75%) of offspring will have red eyes. 1/4 25% are h0m0zygous recessive (rr), and will therefore have the other eye color (question doesn't mention which colour this is, it is likely brown)
