1. Name two biological processes that require cell division
2. Describe the relationship between the following terms: Chromosome, DNA and gene.
3. Why do you think it’s important that the DNA is copied before a cell divides?
Answer:
1.) Mitosis and Meiosis
In mitosis, a somatic cell divides in order to create two identical daughter cells. In meiosis, a germline cell divides twice to create four gametes.2.) A chromosome consists of two sister chromatids, each made up of tightly wound DNA. On these DNA strands are genes, which are specific sequences of nucleotides.
3.) It is important that the DNA is fully copied before the cell divides because cells always need DNA. If the DNA is not copied, one of the new daughters cells would not contain any DNA. Without DNA, the cell will no longer have the instructions necessary to perform its normal functioning.

Which level of producers or consumes would be MOST affected by trace amounts of pesticides, like DDT, that run off into lakes, streams and ponds
The secondary level of consumers will be affected trace amounts of pesticides, like DDT, that run off into lakes, streams and ponds.
What are ProducersProducers are mainly plants that undergo photosynthesis to produce carbohydrates and oxygen.
ConsumersConsumers are herbivores or canivores or omnivores that feed on primary producers like plans and others.
Consumers can be primary which feed on plants examples are goats.Secondary consumer are canivores that feed on meat of other animals, they feed on primary consumer.Tertiary consumers feed on both plants and meat of other plants.Therefore, The secondary level of consumers such as fish will be affected trace amounts of pesticides, like DDT, that run off into lakes, streams and ponds because they live in water and their food is in water. Once the substances are in their water, it will become toxic and can lead to their deaths.

In the central dogma, the rna-to-protein step is termed.
Answer:
translation
Explanation:
a process called translation uses this mRNA as a template for protein assembly. In fact, this flow of information from DNA to RNA and finally to protein is considered the central dogma of genetics, and it is the starting point for understanding the function of the genetic information in DNA.

What is photosynthesis? where does it take place in a plant and what products are produced as a result?
please help me with this question
Answer:
Photosynthesis is when a plant makes food for itself and releases oxygen.
Explanation:
Photosynthesis takes place in the chloroplast of a plant cell, the plant absorbs the light from the sun, takes in carbon dioxide (CO2), and absorbs water from either water on the leaves, or ground water soaked up by plant roots. The light, water, and carbon dioxide get turned into glucose (plant sugar) and oxygen. For humans, they take in sugar and oxygen, and using cellular respiration, they turn the oxygen and sugar into carbon dioxide.

Periods between ice ages are:
A) interglacial periods
B)solar intensity periods
C)due to earth's orbital changes
D)all of the above
Periods between ice ages are:
✒ AnswerA) interglacial periods
The Ice Ages began 2.4 million years ago and lasted until 11,500 years ago. During this time, the earth’s climate repeatedly changed between very cold periods, during which glaciers covered large parts of the world (see map below), and very warm periods during which many of the glaciers melted. The cold periods are called glacials (ice covering) and the warm periods are called interglacials

In a cattle breed, dark red color is incompletely dominant to white. The hybrid condition is roan in color.
What is the % chance of having a dark red calf if two roan cattle are bred?
Answer:
There would be a 60% since the dark red color is incompletely dominant, that would contrast different with the white breed. Having a dark red calf is possible but there can also be in the mid low percentanges.
Which of these does NOT explain why humans and other mammals breathe through lungs, unlike amphibians and other animals that take in oxygen through simple diffusion?
A. Large animals need more oxygen than small ones.
B. Oxygen can only pass through a constantly wet membrane.
C. Mammals have fewer cells than other types of animals.
D. Warm-blooded animals need a lot of oxygen to regulate their body temperatures.
Answer: B
Explanation: Frogs have a moist, permeable skin, which can transfer gasses such as carbon dioxide and oxygen. Humans have dry skin that is impermeable to gas exchange, so almost all gas exchange takes place in the lungs. This means human lungs must be more efficient than frog lungs
Answer:
B
Explanation:
it is so due to osmosis because molecules of oxygen can move through a semi permeable membrane or a permeable membrane and wet membrane is an example
You built this tree using only dna information. Why was examining dna better than considering physical traits?.
DNA is better than considering physical characteristics, because physical characteristics can be confusing and impersonal, since DNA is a unique code, capable of discovering ancestry without error.
What is abridged DNA?DNA (deoxyribonucleic acid) is a nucleic acid that contains all the genetic information of an individual. DNA is a type of nucleic acid that plays a fundamental role in heredity, being considered the carrier of the genetic message.
With this information, we can conclude that DNA is better than considering physical characteristics, as physical characteristics can be confusing and impersonal, since DNA is a unique code, capable of discovering ancestry without error.

Plate tectonic began in 1915 when Alfred Wegener proposed his theory which was continental drift. Usually scientists use waves to study the difference of the layers of earth. They use seismic waves. seismic waves are generated by earthquakes or nuclear-test explosions.
Those 3 pieces would be the fit of the continents, paleoclimate indicators, and geologic features. The rock formations of eastern North America, Northwestern Africa and Western Europe were found later to have a common origin. They were found to overlap.

Founders effect and bottle neck effect are examples of random chance events that result in
variations in the relative frequency of different genotypes in small populations. These are examples
of
codominance
O mutations
O speciation
O genetic drift
Genetic drift is a stochastic process that acts by changing the allelic frequencies of species over time, founders effect and bottle neck effect are examples of this process.
What is genetic drift?It is a stochastic process that produces a change in the allele frequencies within the population, this means that they increase or decrease by chance.
The main genetic effects of a bottleneck are loss of genetic variability and the founder effect can cause traits to become fixed in a species that, in a larger population, never would.
Therefore, we can conclude that founders and bottleneck effects are one of the clearest causes of genetic drift mechanisms, along with resource limitations in a given environment.

What is one situation in which population density could have a negative impact on the production of offspring?
Answer:
Population growth decreases as the population density increases.Explanation:
This may be true for non-human populations but our species has developed the ability to modify the environment to sustain a huge population size.
Population growth decreases as the population density increases. If the individuals of a population are less and spaced widely apart, it may seldom encounter one another, making reproduction rare.
What is population density?Population density can be defined as the average number of people reside in a given area and it is calculated by dividing the total number of people in a certain area by the size of the area.
The measurement of population density is normally represented as the number of people per square kilometer, several physical factors like space constraints, land topography, resources, and climate can affect population density.
Other Human factors like politics, lifestyle, and economics can affect population density; Extreme climate means too cold, hot, wet or dry, too high and too steep, Infertile land
