Explain how cell division allows changes in the DNA of a zygote to be inherited by future generations
Answer:
Explanation:
When cell divides, the DNA will replicate in the parent cell or make copies of itself and this will make the chromatics to split or divide in order to create a new cell or daughter cell which contain the exact same DNA. The daughter cell then pass these DNA to subsequent generations, when it also undergo cell division and the dna is been replicated

Explanation:
An organism because that means a single living thing.
It wouldn't be a biome because that is a certain place for example a forest, the desert etc.

Which sediment has the greatest permeability?
Based on your hypothesis, which population(s) would be hurt if bears were added?
Answer:
The correct answer would be - plants, and small animals like moose, rodents, deer and others as bears are omnivorous animals.
Explanation:
In any forest ecosystem, mostly in the forest ecosystem, beers depend on various kinds of animals and plants for their nutrition and energy. They depend on plants that are rich in berries, fruits, and flesh roots. Beers also eat small animals such as rodents, fishes, and hoofed animals.
Therefore, an increase in the number of beers in any ecosystem will lead to a decrease in the population of these organisms and their population including plants.

A laboratory experiment requires 250 milliliters of water for boiling. It also requires 100 milliliters ofw
process.
horms the experiment three times, how much total water will the student need? Give your answerin
Answer:
550 milliliters of water is needed.
Explanation:
the student will need 550 milliliters of water for completing the whole experiment. 250 milliliters of water is needed for boiling purpose while on the other hand, 100 milliliters of water is needed for one process which can be repeated three times so the process needs 300 milliliters of water so by combining the 250 milliliters and 300 550 milliliters of water we get 550 milliliters of water for the whole experiment so we can say that the student needs 550 milliliters of water for the experiment.

Plants have low energy needs as compared to animals. Explain.
➜ Plants do not move. In a large plant body there are many dead cells like schlerenchyma which provide strength to the plant but do not perform any cellular function. As a result they requires less energy. Animals, on the other hand, need energy for different activities like movement or search or food. So, they require more energy.
➥ Plants have low energy needs as compared to animals because they do not move. Moreover, in a large plant there are many dead cells like sclerenchyma because of which they also need less energy.

A student graphed distance versus time for an object that moves 14 m every 2 seconds. What is the slope of the ling on the graph. Please explain!
Answer:
A slope of 7, representing a speed 7 m/s.
Explanation:
Speed is defined as the distance traveled over time. Mathematically, it's calculated with the equation:
[tex]speed = \frac{distance}{time}[/tex]
Slope of a graph is the rate at which the y and x axis change together, the "rise over the run." Slope can be simply calculated using this equation:
[tex]slope = \frac{x_{2} - x_{1}}{y_{2} - y_{1}}[/tex]
Therefore, when graphing distance versus time, the change in distance is divided by the change in time to find the slope. This is the same as speed.

Answer:
Sperm + egg----- zygote.
Explanation:
During sexual reproduction, a male sperm fuse with female eggs forming a new organism. Male sperm and female eggs have haploid number of chromosomes but when they fuse with each other a zygote will formed having diploid number of chromosomes. The gametes of male and female have haploid number of chromosomes due to meiosis cell division.

Dr. Kettlewell predicted that clean forests would have___________ colored moths, and polluted forests would have ____________ colored moths.
Moth type: Peppered moths.
Answer:
Dr. Kettlebell predicted that clean forests would have light peppered colored moths, and polluted forest would have dark peppered colored moths.
Explanation:
Kettlewell thought that if natural selection caused the change in moth population.
Dark moths resting on light trees were more likely to be eaten by birds then light moths.
Dr predicted the clean forest should have light-peppered and polluted forest have dark peppered.
Role of natural selection:At the time when Dr predicted the clean forest should have light-peppered and polluted forest have dark peppered.
So here the doctor think that the natural selection leads the change in the moth population. Also, the dark moth should be rested on the light trees that eaten by the birds as compared to the light moth.
