How does meiosis relate to haploid cells? How does fertilization relate to
diploid cells?
Answer:
Sexual life cycles involve an alternation between meiosis and fertilization. Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote.
During meiosis Diploid cells divides which gives rise to haploid cells
while During fertilization two haploid cells fuses together which gives rise to offspring carrying a Diploid cell.
Cells found in human body are Diploid cells because they contain 46 chromosomes, while the sexual gametes are haploid cells because the number of chromosomes they possess is half ( 23 ) the number of chromosomes contained in every other body cell .
Meiosis is a cell division process whereby a parent cell is broken down into four gametes with each gamete containing half the number of genetic material/chromosomes contained in the parent cell.
Hence we can conclude that During meiosis Diploid cells divides which gives rise to haploid cells while during fertilization two haploid cells fuses together which gives rise to offspring carrying a Diploid cell

Complete question:
After you complete college, you decide to marry an entomologist. While on your honeymoon with your spouse in Costa Rica, you come across a new insect species. Upon getting approval from the Costa Rican government, you and your entomologist take a few male and female insects back to the US so you can study them. You pick a female insect with a purple body and green eyes, while your spouse chooses a male insect with an orange body and brown eyes. Back in the lab, you and your spouse breed the insects so that you, a geneticist, can understand how body color and eye color are inherited among this newly discovered species. Your crosses results in the following progeny:

if you were to design an organism, what 3 organ systems would be the most important to include?
Plants, like all organisms, adapt to the conditions of their environment. Some special challenges a plant may face are drought, flooding, and a salty environment. Your task is to identify and describe ways that plants adapt to these challenging conditions in their environment. Select one plant adaptation to drought, one adaptation to flooding, and one for salt tolerance. Explain how each adaptation enhances plant survival. Identify a scholarly source of information for each. Use quotes appropriately; be sure your responses are written in your own words
Answer:
Hydrophytes is flood tolerant plants, barley is salt tolerant crop and sorghum is a drought tolerant crop.
Explanation:
Hydrophytes also known as flood tolerant plants that have adaptations to survive flood problems. The plant has the development of air spaces in the roots and stems which allow diffusion of oxygen from the aerial portions of the plant into the roots. Barley shows a greater degree of salt tolerance by applying method of osmoregulation which helps the plant to tolerate salt stress. Sorghum is a plant that is adapted to drought condition. These plants have less number of stomata and waxy layers on the leaves which lowers the rate of evaporation or transpiration.

The drift nets are no longer used them because of its negative effect on the marine animals. These nets catch more than just fish, they could catch dolphins, whales, and many other species that leads to decrease their population and could be an endangered specie. So due to its negative effect on the marine animals, the drift nets have been banned in many countries.
Create a food chain that contains four organisms from a producer through three consumers using corn, rabbit, grass, wolf, snake, eagle, grasshopper, Fox, rat, and hawk.
Answer:
Corn → rat → hawk → wolf
Explanation:
A food chain is a linear relationship that shows the feeding pattern of different organisms. The food chain portrays which organism located in one trophic level eats another. A forward arrow (→) is used to show that the organism after the arrow feeds on the organism before the arrow.
Every food chain starts with an organism called PRODUCER, which is capable of supplying the energy that is transferred from one organism to another. The energy moves along organisms called CONSUMERS as they feed on one another. According to this question, the below food chain shows the feeding relationship between four organisms:
Corn → rat → hawk → wolf
Note that, corn is the PRODUCER, while rat, hawk and wolf are CONSUMERS
Describe an adaptation to a plant's physical characteristic and explain how this adaptation helps the plant survive.
The development of stomata that are closed in arid conditions is an adaptation in plants. It allows plants to survive.
What is evolution?Evolution can be defined as descendence with modification, a process that involves natural selection.
Natural selection refers to the differential survival and reproduction of the more adapted organisms in a population.
Adaptations are specific features that allow organisms to have higher fitness in a population.
Stomata are structures for the interchange of gases (CO2 and O2) from the environment and can be closed to avoid water loss.

To live in a hot desert environment organisms have to be adapted to
Desert animals must adjust to the extreme heat, lack of water, and harsh conditions.
What is adaptation?The process of adapting involves modifying something or your behavior to suit a new environment or purpose. The majority of living things can adapt when forced to.
Desert animals have to adapt to the intense heat, scarcity of water, and challenging environment.
The evenings, when it is cooler, are the only times of day where many desert creatures are active. To escape the severe conditions during the day, some animals burrow.
In deserts, animals live underground or take refuge in burrows during the sweltering summer months.
Some organisms do not require much, if any, water consumption because they obtain the moisture they require from their diet. Others occupy the desert's periphery, where there are more plants and places to hide.
Thus, this way, the organism adapt the extreme environment of desert.

The mutation rate in bacteria is about 3 nucleotide changes per 10 billion nucleotides per cell generation. Under laboratory conditions, bacteria such as Escherichia coli can divide and double in number about every 40 minutes. If a single Escherichia coli cell is allowed to exponentially divide for 24 hours in this manner, how many mutations would you expect to observe on average in the genome (5 million nucleotides) of each of the resulting bacteria compared to the original cell
Answer:
About 0.05 mutations
Explanation:
Given that:
The no. of mutations per generation = 3 nucleotide changes per 10 billion or 3 per 10000 million.
For 5 million nucleotides; we have = (3/10000) × 5 = 0.0015
For 24 hours i.e 36 generations; we have:
= 0.0015 × 36
= 0.054 mutations
A female guinea pig that was pure-breeding for white fur, mated with a male guinea pig
that was pure-breeding for brown fur.
All the offspring had brown fur.
One of the male offspring mated with a female with white fur.
What proportion of white offspring would be expected from this cross?
one half
none
one third
O one quarter
Answer:
one half
Because they both were pure breed (bb and BB) and all the offspring came out as brown that means that brown is the dominant trait. So the offspring are all Bb and if the offspring mated with a white fur she would have to be bb meaning their children woild be either Bb or bb

a, a permanent thermocline traps nutrients in the deep water
b. primary productivity is high all year round, because there is a constant supply of solar energy for
photosynthesis
c, the thermocline disappears in the winter
d. the upper and lower layers of water mix all year round
Answer:
a, a permanent thermocline traps nutrients in the deep water
b. primary productivity is high all year round, because there is a constant supply of solar energy for photosynthesis.
Explanation:
Thermocline occurs in the tropical regions because the temperature is very high which warms the upper layer of water bodies whereas the lower layer of water has low temperature due to no sunlight. The primary productivity is high all year in the tropical regions, because there is a constant supply of sunlight that is needed by the plants for preparing their own food.
