Answer:
B. Both daughter cells are stem cells at this point and are smaller than the parent cell.
Explanation:
The embryo passes through several consecutive cell divisions. With each division, the daughter cells become smaller in relation to their mother cells. In addition, these cells are embryonic and can be called pluripotent. This is because they have the ability to transform into any type of cell that the human body needs, including tissue cells.

in what ways can nitrogen gas be broken down into nutrients for plants
Answer:
it can be done by oxidation and reduction.
Some nitrogen fixing bacterias are also responsible for converting atmospheric nitrogen into nitrates that plants can use (e.g ribozhium )
bacterias in the soil participate in nitrification as well, oxidizing ammonium ions into nitrates which plants can use.
Explanation:
Oxidation produces nitrate compounds
reduction produces ammoniacal compounds.

Mendel’s pea plants had either purple or white flowers. This means that the plants A)can self-pollinate. B)have two recessive traits. C)have two alleles for the gene. D)have two copies of a gene from one parent.
Answer: C) Have two alleles for the gene
Explanation:
Mendel’s pea plants had either purple or white flowers. This means that the plants have two alleles for the gene.
What were the two colors of Mendel's pea plants?Pea colour (green or yellow) Pod shape (constricted or inflated) Pod colour (green or yellow) Flower colour (purple or white).

A sexually reproducing animal has two unlinked genes (on separate chromosomes), one for head shape (H) and one for tail length (T). Its genotype is HhTt. Which of the following genotypes is possible in a gamete from this organism assuming no errors in meiosis?
a) HT
b) Hh
c) HhTt
d) T
e) tt
Answer:
a) HT
Explanation:
This question shows an animal with two distinct unlinked genes i.e. on different chromosomes. One gene codes for head shape and the other for tail length. The gene for head shape possess alleles H and h, while gene for tail length possess alleles T and t.
According to Mendel's law of independent assortment, the alleles of a gene will separate into gametes independently of the alleles of another gene. This occurs in such a way that each gamete will contain only one allele from a gene.
Based on this principle, an animal with genotype HhTt will undergo meiosis and randomly produce gametes with the following allelic combinations: HT, Ht, hT, and ht. As seen in the gametes, only one allele of a gene occured in a gamete at a time.
Therefore, HT is the genotype possible in a gamete of parent: HhTt.

Based on this information, what is the highest magnification power that Stella's microscope can achieve?
Answer:
400 x
Explanation:
The highest magnification power of Stella's microscope is 400 x. magnification refers to the enlargement of size of an object. Due to this magnification, parts of the identified object such as cell can be seen clearly. 400 X means that the cell size is maximize up to 400 times as compared to its original size. Different microscope has different magnification power. The highest magnification power of light microscope is 1500x while the highest magnification power of electron microscope is 10,000,000x.

C. Hormones
D. Enzymes
Answer:
C: Hormones
Explanation:
hormones do not "signal" other cells. I hope this helps :)
The correct answer is option C. Hormones.
What is the simple definition of hormones?Hormones are chemicals that act like messenger substances in the body. After being made in one part of the body, they move to other parts of the body, where they help control how cells and organs work. For example, insulin is a hormone made by the beta cells of the pancreas.
In endocrine signaling, signaling molecules (hormones) are secreted by specialized endocrine cells and transported through the circulatory system to affect target cells in remote parts of the body.
Hormones are so many essential parts of your body's system that they regulate much of what your body does. Hormones regulate growth, libido, sexual development, reproduction, sexual function, metabolism, and thirst, among other things. They simply tell the body what to do to keep it running smoothly.

Read the passage from “Part of the Stew.” On the morning of January 8, 1815, the Redcoats made their attack. Mama and I woke up to the sound of it. It was like thunder that rolled on and on, and we held hands as we thought of Pa and our friends. Then, suddenly, everything was silent. It felt like forever as we waited for news. Finally, word came around that the British had raised the white flag of surrender. The use of first-person point of view helps engage readers by allowing them to experience how the narrator feels about the battle. the narrator’s pa feels about the battle. the narrator’s friend feels about the battle. the narrator’s mama feels about the battle.
Answer:
how the narrator feels about the battle.
Explanation:
The first-person point of view is one of the methods used as a medium for telling the story. In this method, the story is told from the point of view of the person who is a character. All the other characters, events, and settings of the story are told from the narrator's point of view. The story is narrated by using the first person pronouns 'I' and 'we'.

which of these changes in the food web would cause a decrease in the population of bald eagles
The correct answer is C. A decrease in the population of sea ducks
Explanation:
Food webs are diagrams that represent the relationship of organisms in an ecosystem by showing feeding or predatory relationships. This means food webs show which organisms eats another organism. In the case of the food web presented, this shows bald eagles fed on sea ducks and large piscivorous fish, this implies for survival bald eagles need from these two organisms. In this context, a decrease in the population of sea ducks (option C) would cause a decrease in the population of eagles because fewer sea ducks imply less food for eagles, and therefore fewer resources to survive.

A image of Archaea micro organism within the video confirmed that the body is made of a unmarried cellular, and has a described boundary. Scientists also realize that it reproduces by transmitting its genetic facts because there's proof of Archaea genes in our DNA nowadays.
The three traits of lifestyles that Archaea micro organism have are:not unusual characteristics of Archae bacteria known to this point are: (1) the presence of a feature of tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan mobile partitions, in most instances, in preference to a huge protein-wealthy coat; (three) the formation of ether-related lipids formed through phytanyl chains.
what's the difference among micro organism and archaea micro organism?Like micro organism, archaea have no inner membrane however both have cellular partitions and use flagella for swimming. Archaea differs from the reality that their cell wall does not include peptidoglycan and that the cell membrane makes use of ether-linked lipids rather than an ester connected to lipids in micro organism.
