Explanation:
In microscopy, the objective lenses are the optical elements closest to the specimen. The objective lens gathers light from the specimen, which is focused to produce the real image that is seen on the ocular lens. Objective lenses are the most complex part of the microscope due to their multi-element design.
In the Galapagos Islands, there were many species of tortoises, woodpeckers and other animals. Why were the animals like the tortoises so different in appearances, when they lived on neighbor islands?
Answer:
The animals were different because there were things the animals need to adapt to in the Galapagos that may have changed their appearance. for example a bird may have a different shaped beak because they started to evolve so they could eat foods that were available to them on the island

Explain why harmful mutations tend to disappear, while beneficial mutations become
widespread.
Answer:
Harmful mutations don't accumulate over time because they reduce the reproductive success of an organism! These mutations would be dead before they can produce any offspring, so there's a slim chance of their genes being passed on. (So it's basically like survival of the fittest, the ones that survive usually have beneficial mutations because that's what keeps them alive lol) Beneficial mutations play a big role in evolution too!

WILL GIVE BRAINLISTTTT!!!! In what ways are mechanical, chemical and biological weathering responsible for changes in our environment?
Answer:
Mechanical weathering, also called physical weathering and disaggregation, causes rocks to crumble. Water, in either liquid or solid form, is often a key agent of mechanical weathering. For instance, liquid water can seep into cracks and crevices in rock. If temperatures drop low enough, the water will freeze.

The Central Dogma of Biology describes a two-step the process of DNA-RNA-Proteins. Which process is being observed in the diagram below?
The process shown in the given image is transcription. The correct option is 3.
What is transcription?In genomics, transcription is the process of creating an RNA copy of a gene's DNA sequence. This copy, known as messenger RNA (mRNA), transports the protein information encoded in the gene's DNA.
The process of copying a segment of DNA into RNA is known as transcription.
Messenger RNA is created when segments of DNA are transcribed into RNA molecules that can encode proteins. Other DNA segments are copied into RNA molecules known as non-coding RNAs.
The process of copying DNA to RNA is known as transcription, and the process of using RNA to make proteins is known as translation.
Thus, the correct option is 3.

Why is an imbalanced high population of moose on the island seen as a
problem? *
If the moose population continues to grow, they will run out of space on the island and
take over the wolf niche.
If the moose population is unchecked, the local balsam fir population will be
decimated, leaving a barren ecosystem.
It was not seen as a problem; science believes we should let the ecosystem run its
course and dies out.
It was not seen as a problem because the absence of wolves on the island ensured
the future of the ecosystem.
Answer:
If the moose population is unchecked, the local balsam fir population will be decimated, leaving a barren ecosystem.
Explanation:
The imbalanced high population of moose on the island seen as a problem because it decreases the local balsam fir population which is a major food source for the moose in the winter season. If the population of moose is grow higher then the scarcity of food sources occurs and the food source will be eliminated from that ecosystem. If the moose population increases the local balsam fir population will be eliminated from the ecosystem and the land will remain barren or without vegetation.
Describe how each of Newton’s laws may be observable during a car trip.
If the seat belts on any passengers are fastened, the vehicle will also slow down until everyone is at rest. Additionally, if a car was moving straight when another car struck it, the direction of the car would shift.
What are newton's three law of motions ?According to the first law, until a force acts on an item, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration. According to the third law, when two objects interact, they exert equal-sized and opposite-direction pressures upon one another.
There's a fourth law , it states that every object tends to remain in the state it is in right now. We refer to this propensity as inertia. Every object tends to remain in the state it is in right now.
Therefore, If the seat belts on any passengers are fastened, the vehicle will also slow down until everyone is at rest (First law) . Additionally, if a car was moving straight when another car struck it, the direction of the car would shift (Third law).

Explain how and why you would conduct a study to determine if this bone can be used to determine sex
Answer:
The pelvis is the best sex-related skeletal indicator, because of distinct features adapted for childbearing. The skull also has features that can indicate sex, though slightly less reliably. Males have a square jawline and the line between the outer edge of the jaw and the ear is vertical. Conversely, in females the jaw is much more pointed and the edge of the jaw slopes gently towards the ear.

Explanation:
If the species is becoming resistant to the weed killer, natural selection will cause future generations to become resistant as well, therefore the percentage of resistant dollar weed will increase. Also I took the test lol.
Why do plants of the fields become yellowish?
Answer:
Poor drainage or improper watering
Explanation:
Water issues — either too much or too little — are the leading reason behind yellow leaves. In overly wet soil, roots can't breathe. They suffocate, shut down and stop delivering the water and nutrients plants need. Underwatering, or drought, has a similar effect.

which type of traits are responsible for evolution?
Answer:
In biology, evolution is the change in the inherited traits of a population from generation to generation. These traits are the expression of genes that are copied and passed on to offspring during reproduction. ... Genetic drift arises from the role chance plays in whether a given individual will survive and reproduce.
Heredity - This is the passing on of traits from parents to their offspring either through sexual reproduction or asexual reproduction.

Which scenario would result in a decrease in population size, or a negative population growth?
Use this formula:
population growth = (birth rate + immigration) – (death rate + emigration)
0 individuals emigrate, 14 individuals die, 14 individuals are born, 14 individuals immigrate
40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate
12 individuals emigrate, 5 individuals die, 17 individuals are born, 0 individuals immigrate
19 individuals emigrate, 4 individuals die, 25 individuals are born, 0 individuals immigrate
Answer:
The third situation has the lowest amount of people with 0.
Explanation:
In this situation,
0 individuals emigrate, 14 individuals die, 14 individuals are born, 14 individuals immigrate. Population growth = 14
In this one,
40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate Population growth = 2
For this one,
12 individuals emigrate, 5 individuals die, 17 individuals are born, 0 individuals immigrate Population growth = 0
Last one,
19 individuals emigrate, 4 individuals die, 25 individuals are born, 0 individuals immigrate Population growth = 2.
