Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. ... The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
Explanation:
Unlike in mitosis, the daughter cells produced during meiosis are genetically diverse. Homologous chromosomes exchange bits of DNA to create genetically unique, hybrid chromosomes destined for each daughter cell

whats the structure AND location of meninges
Answer:
The meninges is a layered unit of membranous connective tissue that covers the brain and spinal cord. These coverings encase central nervous system structures so that they are not in direct contact with the bones of the spinal column or skull.
Explanation:
Answer:
The dura mater is the outermost layer of the meninges, lying directly underneath the bones of the skull and vertebral column. It is thick, tough and inextensible. Within the cranial cavity, the dura contains two connective tissue sheets: Periosteal layer - lines the inner surface of the bones of the cranium.

4. Species interact with each other in their environments. Describe the relationship between the two species of
barnacles and the snail species. Use the words: symbiosis, predation, competition, fundamental niche, realized
niche.
|
Answer:
Predation is the relationship.
Explanation:
Predation is the relationship present between the two species of barnacles and the snail because snails feed on barnacles for their living. In the fundamental niche, the snail grow in population due to availability of suitable environmental conditions, but when there is realized niche, predation and competition exists which limits the growth of the population of organism. Here barnacles population is limited due to presence of snail which feeds on it.
Select the statement(s) that support bird beak adaptations as
supporting evidence for the theory of natural selection.
-The top bird with a beak adapted for
insect eating would not succeed on a
Galapagos Island with little insects but
plentiful seeds.
-The middle bird with a woodpecker
beak adapted for seed eating most
likely could dig deeper for larger,
harder covered insects more
successfully than the top bird with the
insect eating beak.
The bottom right bird with a beak
adapted for seed eating would succeed
on a Galapagos Island with plentiful
insects but little vegetation.
The bottom right bird with a beak
adapted for seed eating would succeed
on a Galapagos Island with plentiful
vegetation and few insects.
Answer:
-The top bird with a beak adapted for insect eating would not succeed on a Galapagos Island with little insects but plentiful seeds.
-The middle bird with a woodpecker beak adapted for seed eating most likely could dig deeper for larger, harder covered insects more successfully than the top bird with the insect eating beak.
-The bottom right bird with a beak adapted for seed eating would succeed on a Galapagos Island with plentiful vegetation and few insects.
Explanation:
The theory of natural selection explains that organisms undergo changes in their physical and genetic features that make it possible for them to adjust to their environments. There are different types of birds having different shapes of beaks adapted for life in several environments.
There are insectivorous birds whose beaks are adapted for eating insects, granivorous birds with short, conical beaks for cracking seeds, frugivorous birds adapted for eating fruits, nectivorous for sucking nectars, among others. The adaptations are unique to the birds and determine their survival and feeding habits in several environments.

Compare the practices of shelterwood cutting, clearcutting, and seed-tree cutting.
Answer:
Clearcutting removes all the trees within a certain area at one time. Shelterwood cutting also removes all the trees in an area, but does it in stages over several years. Seed-tree cutting removes all the trees except for a select number of mature trees that can then reseed the area.
Explanation:
Clearcutting removes all the trees within a certain area at one time. Shelterwood cutting also removes all the trees in an area, but does it in stages over several years. Seed-tree cutting removes all the trees except for a select number of mature trees that can then reseed the area.
What happens in the process of clearcutting?Clearcutting removes all the trees within a certain area at one time. Shelterwood cutting also removes all the trees in an area, but does it in stages over several years.
Seed-tree cutting removes all the trees except for a select number of mature trees that can then reseed the area. Seed-tree cutting and shelterwood cutting allow for the harvested areas to recover over time without direct intervention.
The scale of clear-cuts throughout Oregon is limited by law, although proprietors have been required to leave trees throughout specified locations to preserve waterways as well as provide wildlife habitats.
Therefore, Clearcutting removes all the trees within a certain area at one time. Shelterwood cutting also removes all the trees in an area, but does it in stages over several years. Seed-tree cutting removes all the trees except for a select number of mature trees that can then reseed the area.

Testes in man and ovary in female is a part of the reproductive organ which produce gametes, after fertilization to develop a baby, hence c is the correct option.
What are reproductive organs?
Female reproductive organs consist of the ovary which generates the ovum a female gamete that is responsible for fertilization.
Males consist of consisting of tests that generate the sperm male gamete which is responsible for fertilization.
Both organs are necessary to produce a gamete for fertilization which develops a zygote and makes the baby is developing of the cells.
Therefore, for producing sex cells ovaries and testes are important organs, hence option c is correct.

when does a mutation affect the offspring?
Answer:

Explanation:
Name one way that each of the three food
production systems (crops, meat, and fish/shellfish) can result
in environmental problems.
Answer:
Crops: Contamination by uncontrolled use of chemicals such as pesticides and fertilizers. Deforestation.
Meat: Water pollution with animal wastes, chemicals, and other toxic and contaminants. Deforestation.
Fish: Overfish and accessory capture.
Explanation:
Crops: Industrial farms make unconscious use of pesticides and fertilizers that penetrate the soil contaminating it, polluting water, and affecting plants and animals that live around that land and beyond. Animals and people exposed to pesticides such as insecticides, fungicides, and herbicides, have been shown affected by their effect.
Meat: Meat production turns to be one of the principal causes of water and soil pollution. Contaminants originate mostly from animal wastes (dung, blood), antibiotics, hormones, chemical substances used in the tannery, and sediments of eroded soils.
Both industries play a principal role in global deforestation. Most native forests get cut down to make a place for the development of these activities.
Fish: Overfish is one of the most important environmental problems caused by fisheries. Uncontrolled resource overexploitation leads to species´ extinction. Huge amounts of animals get caught in any of their stages of development. Young animals do not reach the reproductive stage, and reproductive females can not release eggs. This causes important damage to the reproductive rate of the species. Also, when overexploiting, many other unwanted species get caught and die on the nets. Accessory capture is the cause of death of many invertebrates, fishes, and marine mammals die because of the fisheries nets.
The three food items like crops, meat, and fish can lead to environmental problems by the release of GHG, overconsumption, and land degradation.
What aspect of the food items of the production system harm the environment. ?The food production system like the crops can lead to an increase of gases and removal of forest lands that leads to less habitat for wildlife. The production of meat either sheep, cow, buffalo, etc. will lead to the release of the GHG and increased resource depletion.
Overfishing will lead to the tragedy of commons and similar these aspects will lead to land degradation by excessive utilization of resources. Hence impacting the environment.
