Which of these is an example of a haploid cell?
Answer:
Gametes
Explanation:
Gametes are an example of a haploid cell and are produced as a result of meiosis.
2. If a nucleus has 8 chromosomes, how many chromosomes will be present after Telophase I? 3. What advantage does crossing-over have in reproduction? 6. Compare and contrast spermatogenesis and oogenesis (where do they occur, how many gametes are formed, when do they develop, etc):
Answer:
Telophase I: 8 chromosomes composed of two sister chromatids
Crossing over refers to the mechanism of recombination, this process being characterized in that increases the genetic variation
Spermatogenesis refers to the mechanism of formation of male gametes (sperms), while oogenesis is the process of formation of female gametes (oocytes)
Explanation:
Telophase I is the final step in meiosis I. During telophase I, the nuclear membrane is formed around the decondensed set of chromosomes and the nucleoli reappear.
Spermatogenesis refers to the process by which haploid male germ cells (sperms) are generated within the seminiferous tubules in the testis, while oogenesis refers to the process of differentiation of the female egg cells (ova or oocytes) in the ovaries. Spermatogenesis is known to produce small and motile spermatic cells, while oogenesis is known to produce bigger non-motile oocytes.
Angiosperms (flowering plants) and vertebrates obtain nutrients from their environment in different ways. a. Discuss the type of nutrition and the nutritional requirements of angiosperms and vertebrates. b. Describe 2 structural adaptations in angiosperms for obtaining nutrients from the environment. Relate structure to function. c. Interdependence in nature is evident in symbiosis. Explain two symbiotic relationships that aid in nutrient uptake, using examples from angiosperms and/or vertebrates. (Both examples may be angiosperms, both may be vertebrates, or one may be from each group.)
Answer:
a. Angiosperm are plants (autotrophs) that use photosynthesis to produce their own food, while vertebrates are animals (heterotrophs) that obtain their food from other organisms. Vertebrates include fish, amphibians, reptiles, mammals and birds.
b. Adaptations in angiosperms include two reproductive structures 1- fruits (ovaries), whose main function is to disperse the seeds and 2- flowers that ensure pollination and protect the embryo sac during its formation.
c . Examples:
1- The mycorrhizal symbiosis between plant roots and symbiotic fungi plays a key role in nutrient uptake from the soil. Arbuscular mycorrhizal is a type of symbiosis where a fungus of the phylum Glomeromycota penetrates the cortical root cells of vascular plants to produce specialized structures named arbuscules.
2- Microflora in the vertebrate digestive tract. The microorganisms that live in the digestive tract of vertebrate species are beneficial for the absorption of nutrients. For example, in humans, Saccharomyces boulardii has shown to have a probiotic effect by increasing intestinal homeostasis, thereby enhancing nutrient uptake.

a strand of dna contains the base sequence AGTT . What is the sequence of the complimentary strand of DNA
Answer:
The sequence is TCAA
Explanation:
Deoxyribonucleic acid (DNA) is a molecule composed of two complementary chains of nucleotides. The nucleotides are in turn composed of one nitrogenous base, one deoxyribose sugar, and one phosphate group. The four different types of nitrogen bases found in DNA are thymine (substituted by Uracil during RNA transcription), adenine, cytosine and guanine. These bases bind by complementary base pairing to form an antiparallel double-strand. The complementary base pairing rule states that thymine forms two hydrogen bonds with adenine, while cytosine forms three hydrogen bonds with guanine.
Answer:
TCAA
Explanation:
A matches to T and G matches to C.

The uterine cycle describes the cyclic changes of thickening and degeneration that the endometrium goes through in a month. What is the order of events in one uterine cycle
Answer:
During the uterine month there are different phases through which the uterus passes, these phases are regulated by hormones and are responsible for producing the cycle necessary for fertilization.
Phase where menstruation occurs: This phase only happens if the woman was not fertilized and did not develop the diploid cell together with a sperm, since not being fertilized, all the uterine preparation that had been planned in the body for fertilization will be released as that we know "menstruation", in this phase estrogens and progesterone are low. The inner walls of the unfertilized uterus are released.
Follicular phase, in the follicular phase the ovaries prepare to release an egg and estrogen begins to rise. (From the first day of the period until ovulation)
Proliferative phase, in the proliferative phase, new vessels proliferate and the outermost layer of the uterus prepares itself for possible fertilization, is where spiral arterioles can begin to form again in the external cut of the myometrium.
Ovulation, here is where the mature ovum is called Graff's follicle, at this time estrogen reaches its peak and then descends.
Luteal phase, in the luteal phase the production of the luteal body is generated, at this stage progesterone takes center stage, and it is the range between ovulation and menstruation (if not fertilized)
Last phase, secret phase, in this phase there are two possible ends, if the woman is fertilized, the egg cell implants and begins the development of the embryo and if it is not fertilized, the entire external cut of the myometrium is prepared to be secreted.
Explanation:
A very important fact to clarify is that women are born with a quantity of ovules that at the end of this uterine cycle ceases to exist, this process is what we know as menopause.
That is to say that women have a quantity of ovules that will one day run out, and the body releases them from the menarche or the first menstruation, generating that in each released ovule a uterine cycle is completed, the day they end the woman will have reached menopause and would have no chance of being fertilized or completing the uterine cycle.
superficial layer of the endometrium is shed
basal layer of endometrium grows, forms gland and blood vessels
enriched endometrial blood supply
endometrial glands secrete nutrients into uterus
Where is the last storage location for melted snow? (2 points) Where is the last storage location for melted snow? (2 points) Group of answer choices Rivers Ocean Streams Mountains
Answer:
Ocean
Explanation:
Ice is usually found in the glaciers in the mountains and once it gets heated it flows down through melting and forms a stream and enters into rivers and these streams combine and lead to the oceans. Thus these oceans become the ultimate storage units of melted snow. Ice and cannot stay in solid-state for too long.How can protists exhibit both animal-like and plant-like characteristics?
A heterotrophic and chlorophyll protist
Food is ingested by protists in three forms. We produce, eat and digest their own organic molecules. Meat ingestion or english bacteria ingests protists. The cell wall and cell membrane are stretched to create an alimentary vacuolum around the foodstuff. Enzymes extract the food inside the food vacuole. At the other side, absorbent protists consume food molecules through their cell membrane by diffusion. In decomposition, absorbent protists play a crucial role. They are assumed to be essential decomponents. Light energy is used to make your own food by big farmers including photosynthetic protists.

explain why a father with blood group AB cannot donate for a child with blood group O when he marries a woman with blood group O
The odds are astronomical for a father with AB(IV) to have an O(I) child. The only possible way for this phenomenon to occur is if there was a nondisjunction in the ovogenesis for the 9th chromosome and the father also had a nondisjunction for the same chromosome(A sperm cell with no 9th chromosome fertilized an ovum with two 9 chromosomes).
A person with AB cannot donate to a person with O because the receiver has antibodies(alpha and beta) that bind to the antigens on the AB blood cells, causing death.
Which of these lymphoid organs destroys bacteria before it can breach the intestinal wall and generates "memory" lymphocytes for long-term memory?
Answer:
Peyers patches
Explanation:
Peyers patches are group of lymphoid follicles found in the ileum of the small intestine.
This part of lymphatic system form part of immune system that help to control bacteria population in the small intestine and prevent the growth of pathogenic bacteria in the small intestines. It plays an important role in immune surveillance where it recognises pathogenic bacteria and destroy the bacteria.
It is a lymphoid organs destroys bacteria before it can breach the intestinal wall and generates "memory" lymphocytes for long-term memory because it form the part of the immune system which help to fight infection or foreign substances in the body, also by generating lymphocytes which is a white blood cells of the immune system which generate long term memory of foreign pathogens and destroying it.

Which statement best describes how Watson and Crick's model used other scientists work to create a model of DNA?
They used Chargaff's rule to determine that it contains ribose sugar
O They used Franklin's photo to determine that DNA was a double helix.
They used Levene's work to determine the number of base pairs in each strand.
O They used Nirenberg and Matthei's studies to determine that DNA is made of nucleotides.
Answer:
b.
Explanation:
They used Franklin's photo to determine that DNA was a double helix.
The best statement that describes how Watson and Crick's model used other scientists' work to create a model of DNA can be seen in the second Option.
They used Franklin's photo to determine that DNA was a double helix.
The early 1950s saw the development of the renowned model of the DNA double helix by American scientist James Watson and British physicist Francis Crick. They were the explorers to pass the finishing line in this scientific race.
Rather than doing fresh tests and experiments in the lab, Watson and Crick primarily gathered and evaluated existing data, combining it in novel and illuminating ways.
Franklin was a specialist in X-ray crystallography, a sophisticated approach for identifying molecular structures. When an X-ray beam strikes the crystallized form of a molecule, e.g the DNA, part of the rays are redirected and diverted by the atoms in the crystal, creating a diffraction pattern that unveils data information regarding the structure of the molecule.
Franklin's crystallography provided crucial hints to Watson and Crick on the structure of the DNA model. Some of them originated from Franklin's extraordinarily clear and stunning X-ray diffraction photo of DNA.
According to the work of Phoebus Levene, Levene only posits that the DNA was formed of subunits called nucleotides.
Erwin Chargaff speaks volumes on the determination of the composition of ribose sugar bases.
Therefore, we can conclude that Watson and Crick knew about all these Phoebus Levene and Erwin Chargaff postulates and experiments but it was Franklin's work on X-ray diffraction photos of DNA that gave them a crucial hint to create a model for the DNA.

Why does deleting just one nucleotide cause a dramatic change in the amino acid sequence produced by translation
Answer:
The deletion changes the genetic code.
Explanation:
The sequence of nucleotides determines the order of amino acids in a protein, the order of amino acids determines the shape and the shape determines the function. A very good example of one misplaced nucleotide having tremendous effects is sickle cell disease, where thymine is replaced with adenine(CAC instead of CTC). It means that glutamic acid is replaced with valine. This alters the shape of the protein(Beta chain of hemoglobin). So the red blood cells are deformed and carry a lot less oxygen leading to a lot of symptoms just because of one misplaced letter.
