Which of the following happens because of mitosis? (Check all that apply)
Answer:
1,2
Explanation:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. ... Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.
What should one do if the results of an experiment consistently do not support the original hypothesis?
Answer:
Change the hypothesis to match the results.
Which description is correct for both oogenesis and spermatogenesis?
The cells have 46 chromosomes until meiosis II is completed.
After meiosis I, the cells have 23 chromosomes.
Part of meiosis I is completed before birth.
The entire process takes about 70 days.
Answer:
After Meiosis I, the cells have 23 chromosomes
Explanation:
It is B
In meiosis there is a reductive phase (meiosis I) and the not reductive phase (meiosis II). Option B). After meiosis I, the cells have 23 chromosomes.
What is meiosis?Meiosis is a process by which, from a diploid germ cell (2n), four haploid cells (n) -the gametes, sperm and egg cells- are produced. This is the gametogenesis process.
Each daughter cell has half of the chromosomes of the original one.
There are two phases in meiosis:
the first one in which occurs a chromosome's reduction division, and the second one where the cell suffers a new division, but this one is not a reductive one.So, if the germ cell has 46 chromosomes, after meiosis I each new cell will have 23 chromosomes, because meiosis I is the reductive phase.
Option B is correct.

Define photosynthesis, cellular respiration,
autotroph, heterotroph, herbivore, carnivore,
omnivore
Answer: Omnivore is an animal that eats both plants and animals.
Carnivore is an animal that eats only meat. Herbivore is an animal that eats only plants.
Heterotroph is an organism deriving its nutritional requirements from complex organic substances.
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Autotroph is an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products.

What are the items that attach on the inside of the mineral to give the mineral its shape
Answer:
Molecules.
Explanation:
Molecules are the items that attach on the inside of the mineral to give the mineral its shape. The molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.
Due to the fact that, these molecules are structurally arranged or ordered and are repeated by different symmetrical and translational operations they determine the shape of minerals.
A human skin cell is observed. It is found to have two distinct nuclei each having 46 unreplicated chromosomes. These observations would be seen if the cell is in____.
a. G2 of interphase
b. metaphase of mitosis
c. S of interphase
d. telophase of mitosis
e. prophase of mitosis
Answer:
c
Explanation:
During the telophase stage of mitosis, a cell is observed with two distinct nuclei with 46 unreplicated chromosomes. Thus, the correct option is D.
What is Mitosis?
Mitosis is the process of cell division by which a cell replicates its chromosomes (genetic material) and then segregates that into two daughter cells, producing two identical nuclei in preparation for the division of cell. Mitosis is followed by equal division of the cell's content into two daughter cells with the identical genomes.
During the telophase stage of cell division, the spindle fibers attached to chromatids disappear. Once the daughter chromosomes arrive at the poles, a nuclear envelope starts reappearing around each set of chromosomes. And, at the end of telophase stage of mitosis, there are two nuclei in one cell, known as daughter nuclei that contains an exact copy of chromosomes.
Therefore, the correct option is D.

In DNA, different alleles of a gene have a different sequence of ___________________. Alleles may have a different sequence of ___________________ in RNA that result in a different sequence of _________________ in a protein. Therefore, proteins produced from different alleles of a gene may have different structures and functions and result in different characteristics.
Answer:
blood cotton dna
Explanation:
hahahahahaahahahaha
In DNA, different alleles of a gene have a different sequence of nucleotides. Alleles may have a different sequence of nucleotides in RNA that result in a different sequence of amino acids in a protein. Therefore, proteins produced from different alleles of a gene may have different structures and functions and result in different characteristics.
What are nucleotide?Nucleotides are the building blocks of DNA and RNA. They are composed of a sugar, a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the base thymine is replaced by uracil (U). The sequence of nucleotides in DNA or RNA determines the sequence of amino acids in a protein. Proteins are made up of long chains of amino acids, and the sequence of these amino acids determines the protein's three-dimensional structure and function.
Alleles are different versions of a gene. They can result from mutations or changes in the DNA sequence. Different alleles of a gene can produce proteins with different structures and functions, which can result in different characteristics in an organism. For example, the gene that determines eye color has several different alleles, which can result in different eye colors in people.

Unlike other careers in neurology, all doctors of neurology who want to apply for work in the US must first go through
certification.
licensing.
training.
a background check.
The correct answer is B. Licensing.
Explanation
The Neurologist is a doctor who has specialized in the study of diseases and disorders that affect the nervous system. When a person in the United States wishes to practice as a neurologist, they must follow some steps. You must first prepare to enter medical school by studying an area related to medicine such as chemistry, physics, biology, among others, which conceptually prepares you for the next step. In the second step, you must apply to medical school, where you will be put to the test with the Medical College Admission Test (MCAT) to measure your knowledge on this subject. Once you enter medical school, there you will learn for two years everything related to the necessary concepts and theory about medicine and later you will have to serve as a medical apprentice in university hospitals where you will apply what you learned.
Third, once the doctor has obtained his title that accredits him as a doctor, he must obtain one of the medical licenses that USMLE (United States Medical Licensing Examination) or COMLEX (Comprehensive Osteopathic Medical Licensing Examination of the United States ) doctors must have in the United States. Finally, the doctor must serve for three years as a resident in a hospital focused on an area related to Neurology and one more year of internship. According to the above, the correct answer is B. Licensing.
