1. Name the two processes that occur in meiosis that increase genetic variation
The two factors are: crossing-over and independent assortment. Crossing over: In Prophase I of Meiosis I, homologous chromosomes line up their chromatids and “cross-over”, or exchange corresponding segments of DNA with each other. This produces genetic variation by allowing more combinations of genes to be produced.
a child pushes a toy car. The car rolls were short distance, but friction causes it to slow down and eventually stop. Is it Newton's first law of motion second law of motion or third law of motion
Answer:
3rd law

Explanation:
Imagine a marked increase in dissolved carbon dioxide in warm shallow waters, where coral reefs exist. How could the increase in dissolved carbon dioxide MOST LIKELY affect the diversity of this ecosystem?
Question 4 options:
Aquatic plants die because they are unable to carry out photosynthesis under the new conditions.
The increased carbon dioxide causes an increase in dissolved oxygen also and more animals migrate to the area.
These are perfect conditions for coral reefs, which support a vast diversity of living organisms.
Some organisms are unable to withstand the reduced pH levels and die.
Some organisms are unable to withstand the reduced pH levels and die because the carbondioxide in water makes the water acidic.
What is the effect of dissolved carbondioxide in water?Ocean acidification occurs when the carbondioxide gas is dissolved in water that have negative effects on many marine species especially on coral reef which provides habitat and food for many organisms.
So we can conclude that some organisms are unable to withstand the reduced pH levels and die because the carbondioxide in water makes the water acidic.

Joe When scientists analyze the fossil record, they find organisms that are similar to some organisms of today with noticeable changes. How does this help scientists to
interpret the past?
O A. It doesn't help them at all
B. It allows them to see how organisms have changed over time.
OC. It allows them to see how organisms have remained the same over time.
OD. It allows them to see that there is no relationship between the past and today.
Answer:
B
Explanation:
This allows them to see how organisms have changed over time by comparing fossils to current organisms, which can help scientists understand the organism more and why they lost or gained traits over time
At an incineration facility, 90% of the garbage's volume is lost. The last 10% is in the form of _______.
A: Plasma
B: Ash
C: Sludge
D: Steam
At an incineration facility, 90% of the garbage's volume is lost. The last 10% is in the form of Ash.
What do you mean by Incineration facility?An Incineration facility may be defined as a facility that tolerates municipal solid wastes and disposes of them through the method of combustion.
When this facility tolerates the wastes, approximately 80 to 90% of its volume gets lost. The remaining is left in the form of ash. It is formed just bottom of the incinerator unit.
Therefore, it is mentioned above.

Take a moment to click the start button on the simulation. Let it run for about 1 minute (the clock hand will complete 1 rotation) and then click stop. What did you notice coming from the plant?
a) sugar
b)bubbles
c)flowers
Bubbles are observed in the simulation after 1 minute due to the production of oxygen by plants during photosynthesis.
What is photosynthesis?Photosynthesis is the process by which green plants manufacturer their food from carbon dioxide and water using sunlight as am energy source.
In the process of photosynthesis, sugar is produce and oxygen is given off as a by-product.
Oxygen being a gas produces gas bubbles.
Therefore, in the simulation, bubbles are observed after 1 minute due to the production of oxygen by plants.

Answer:
It depends on the passage or story.
Explanation:
The variations in the lemming population illustrate
A. the impact that population cycles have on predators
B. the ways in which a lack of food drives species to extinction
C. the benefits that generalist predators have over specific predators
D. how land animals have different population cycles than marine creatures
Answer: A) The impact that population cycles have on predators.
Explanation:
When a prey species is rare, food and space are plentiful, and its population increases rapidly. Meanwhile, the population of predators that feeds on it grows only once the prey population is big enough to fuel expansion
The variations in the lemming population illustrate the "impact that population cycles have on predators".
What is lemming populations change?lemming population cycles are driven by the predatory attentions of the least weasel (Mustela nivalis), which in turn shows a 'predator'-type cycle. Although lots of lemmings fall prey to owls, arctic foxes and suchlike, this isn't what makes their numbers oscillate.
What is population cycles ?A population cycle would be a generally periodic change in such a population's size or makeup over time. The population's component structure, such as its division into different age groups, is referred to as composition in this context.

The organisms will be classified as producers, primary consumers, and tertiary consumers respectively.
Trophic levelsThese are the positions of organisms in the food chain in an ecosystem.
Producers are organisms that produce their own foods by photosynthesis. Thus, oak trees are producers.
Primary consumers feed on producers. Moths feed mostly on plant nectars. Some parasites feed on plants while others feed on animals. Thus, parasites can classify as both primary and secondary consumers while moths can only classify as primary consumers.
Secondary consumers feed on primary consumers. Thus, animal parasites will classify as secondary consumers.
Tertiary consumers are usually predators that feed on other animals. Thus, owls and weasels which are known carnivores will classify as Tertiary consumers.

Select the boxes to show the genotypes for each fish shown.
The phenotype of the fish when both R and Bl are present will be Blue and Red while the genotype will be BR.
What is co-dominance?Co-dominance in genetics is the condition in which alleles of a gene are both dominant in that when both are present in an organism, the organism will show the phenotype of both alleles.
