what is embryogenesis???
Answer:
Embryogenesis is the development of an animal or plant embryo.
OR
Embryogenesis is the process of development of an embryo from zygote. In embryogenesis, the zygote undergoes repeated cell division through mitosis. The divisions help in the growth of an embryo. Cells undergo differentiation attaining specific shape, size and function. Cell differentiation occurs at specific location resulting in the production of different tissue, organs and organ system.
At a deep sea whale fall, the Atlantic hagfish, the crustaceans, and the sand make up which of the following?
Answer:
I would say part of an ecosystem and community.
Explanation:
An ecosystem is a biological community of interacting organisms and their physical environment .In the bottom of the sea,there are already many animals living here and when the whale fall appears at the bottom of the ocean it becomes apart of the ecosystem as it provides them with food.
This is because when a whale dies, its body often falls to the seafloor. The whale's body then becomes food and shelter for organisms in the deep sea. This is called a whale fall. A deep-sea whale fall might support 200 different species for as long as 10 years! Larger species, such as Atlantic hagfish, are the first to arrive to feed on the whale flesh. Later, smaller species of snails and crustaceans come to eat the remaining flesh. Worms burrow into the sand beneath the whale body, and bacteria feed on the whale bones.
Answer:
Part of an ecosystem
Explanation:
The Atlantic hagfish and the crustaceans are living organisms. The sand is a nonliving part of the environment. An ecosystem is made up of living organisms and the nonliving parts of their environment. So, the Atlantic hagfish, the crustaceans, and the sand make up part of an ecosystem.

Will give BRAINLIEST
Answer:
Mucous membranes
Explanation:
The epidermis (external) and mucous membranes (internal) represent the first non-specific barriers that act against invading pathogens and harmful substances. The mucous membranes separate the external environment surrounding the mucous cells from the body's internal environment. These membranes are considered as selectively permeable barriers that act to prohibit the passage of pathogenic microorganisms (e.g., bacteria) and harmful agents (toxic chemical substances).
The surprisingly low rates of genetic differences between different current human populations (about only 6.5%) and that most genetic diversity occurs person-to-person within a population rather than population to population points to:
A.
a common origin of Homosapiens sapiens in Africa from a small number of people
B.
a fairly high rate of gene flow between human populations
C.
a fairly short time, perhaps 200,000 years existing as a new species in Africa
D.
all of the above
Answer:
the answer for this question would be B.
a fairly high rate of gene flow between human populations
Genetic diversity is the result of heritable traits that vary within species. It is seen more in person-person than in population because the human population has a high rate of gene flow. Thus, option B is correct.
What are gene flow and drift?Gene flow is the passing of the heritable traits outside and inside the population due to factors like migration or because of the gametes. The alleles possessing the characters are moved from one population to another.
In genetic drift, the allele frequency experiences an alteration in the genetic pool of the population. High genetic flow and the drift in humans result in genetic diversity. It causes very neutral differences to appear and are most likely to be seen in person rather than in the whole population.
Therefore, the high gene flow results in genetic diversity in the person.

photosynthesis, respiration, volcanic eruption, decomposition
Answer:
-> photosynthesis: the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
-> respiration: a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
-> volcanic eruption: Volcanic eruptions happen when lava and gas are discharged from a volcanic. Volcanic eruptions often cause temporary food shortages and volcanic ash landslides called Lahar. The most dangerous type of volcanic eruption is referred to as a 'glowing avalanche'.
-> decomposition: Dead organisms are broken down into smaller pieces by the process of decay.
Explanation:
Hope you get your answer correct!
Have a good day :D
Answer:
Photosynthesis: Photosynthesis is the process by which plants convert light energy to starch and chemical energy to manufacture their own food.
Respiration: Respiration is the process by which a living thing breathes in air. humans breathe in oxygen and breath out carbon dioxide, on the other hand plants breathe in carbon dioxide and breathe out oxygen.
Volcanic Eruption: Volcanic eruption is the process when a volcano sends out lava to the outer surface of the earth due to tectonic plate movements.
Decomposition: Decomposition is the process by which dead organic substances or decaying matters are broken down into simpler organic or inorganic matters with the help of natural processes.

In eukaryotes transcription takes place in the _________. translation takes place in the ________.
1. cytoplasm/cytoplasm
2. nucleus/cytoplasm
3. nucleus/ribosomes
4. ribosomes/nucleus
Answer:
3
Explanation:
The correct answer will be option-Transcription takes place in the nucleus, and translation takes place in ribosomes.
The regulation of genes is regulated and controlled by two main processes of central dogma called transcription and translation.
Transcription is the process of formation of messenger RNA or mRNA from a single strand of DNA whereas translation is the formation of protein from mRNA.
This process takes place in different sites in prokaryotes and eukaryotes. In prokaryotes, both transcription and translation take place in the cytoplasm but in eukaryotes, the transcription takes place in the nucleus whereas translation takes place in the ribosomes present in the cytoplasm.
Thus, the selected option is the correct answer.

Complete question:
If an increase in dicynodont species diversity (in other words, number of species) occurred soon after the Permian extinction, and if it occurred for the same general reason usually given for the increase in mammalian diversity following the Cretaceous extinction, then it should be attributed to
A) an innovation among the dicynodonts that allowed them to fill brand-new niches.
B) the availability of previously occupied niches.
C) the extinction of the dinosaurs (except the birds).
D) their out-competition of many other terrestrial organisms.
Answer:
B) the availability of previously occupied niches.
Explanation:
Some species could survive massive extinctions caused by severe natural catastrophes. Some of them were small animals that could hide in certain places that were useful for their protection during the catastrophe. Those animals, that for instance, could hide underground, were able to avoid extreme temperatures and highly toxic gas concentrations caused by the phenomenon. Catastrophes caused severe damage to the Earth´s surface, causing the extinction of many other animal and vegetal species, causing changes in the morphology of the ground, and in temperature. Animals that could survive found themselves in a whole different place. Many niches were now available to be re-occupied. Survivers could specialize in different feeding strategies, finding new different shelters, and developing new morphological characteristics that lead to a rapid diversification and speciation.

Duchenne Muscular Dystrophy (DMD) is a sex-linked trait that causes muscular weakness that gets worse as a person ages. Which is most likely true of Duchenne Muscular Dystrophy? A. DMD can only be inherited by females. B. Females with DMD always have a mother with DMD. C. The gene for DMD is located on the X or Y chromosome. D. The gene for DMD is most active in the cells of the reproductive organs.
Answer: C
Explanation:
DMD is s*x linked trait. This means that we have to consider the chromosomes XX and XY. For a male to have DMD, this means the mom must must pass down the allele for DMD. The mom can either be a carrier OR she has to have DMD and the dad can only pass down the Y chromosome. For a daughter to get DMD, this means the dad has to have the allele for DMD and so does the mom. That means that the dad has DMD and the mom can either have DMD or be a carrier. Based off of this logic, we know that the answer isn't B. Because they tell us DMD is s*x-linked trait, it means that the gene for DMD is on the x or y chromosome.
