TRUE/FALSE. 1. a bacterium is discovered with new mutated form of isocitrate dehydrogenase that catalyzes the same reaction but produces hydrogen gas instead of nadh.
It is a False statement that a bacterium is discovered with a new mutated form of isocitrate dehydrogenase. Isocitrate dehydrogenase is an enzyme involved in the citric acid cycle.
Its main function is to convert isocitrate into alpha-ketoglutarate while producing NADH as a byproduct.
The conversion of isocitrate to alpha-ketoglutarate involves the removal of a carboxyl group and the addition of a water molecule.
This reaction is important for the production of high-energy electrons in the form of NADH, which can be used in the electron transport chain to generate ATP.
Hydrogen gas production would require an alternative reaction pathway, which is not associated with isocitrate dehydrogenase.

The nucleotide sequences found in two different species are made of the same base pairs. This is evidence of
Answer:
The correct answer is - closely related species.
Explanation:
If two species have similar gene sequences or nucleotide sequences with the same base pairs then it means they both are closely related and have diverged from a similar and latest ancestor.
The same gene sequence results in the same proteins that could result in the same phenotypic behavior. Such cases establish that both species are closely related and have recently diverged. These species must have a common ancestor.
during meiosis, a nondisjunction event results in a gamete with one too few chromosomes. after fertilization of that abnormal gamete with a normal gamete, the resulting human zygote will have how many chromosomes?
After fertilization with a normal gamete, a human zygote resulting from a nondisjunction event during meiosis will have 46 chromosomes.
When a nondisjunction event occurs during meiosis, it means that chromosomes fail to separate properly, resulting in a gamete with an abnormal number of chromosomes. In this case, a gamete with one too few chromosomes will be produced. This gamete will have 23 chromosomes instead of the normal 24.
After fertilization with a normal gamete, the resulting human zygote will have 46 chromosomes, which is the normal number of chromosomes in a human cell. This is because the normal gamete will contribute its 23 chromosomes to the zygote, which will combine with the 23 chromosomes from the abnormal gamete.
It's worth noting that nondisjunction events can also result in gametes with one too many chromosomes, which can also lead to genetic disorders in the resulting zygote. These disorders can include Down syndrome, Turner syndrome, and Klinefelter syndrome, among others.

georges-louis leclerc was an eighteenth-century taxonomist who developed the binomial system of nomenclature. true or false
The statement "Georges-Louis Leclerc was an eighteenth-century taxonomist who developed the binomial system of nomenclature" is false because it was Carl Linnaeus, an 18th-century Swedish botanist, who developed the system.
Georges-Louis Leclerc, Comte de Buffon (1707-1788), was an important figure in the field of natural history during the eighteenth century, but he did not develop the binomial system of nomenclature.
The binomial system of nomenclature was actually developed by the Swedish botanist and physician Carl Linnaeus (1707-1778). Linnaeus is considered the father of modern taxonomy and is known for his work in establishing a standardized system for naming and classifying organisms.
In Linnaeus's binomial system, each organism is given a unique two-part scientific name consisting of its genus and species. This system, known as binomial nomenclature, provides a universal language for identifying and categorizing species, and it is still widely used in biological sciences today.
While Georges-Louis Leclerc, Comte de Buffon, made significant contributions to the field of natural history, he focused more on broader concepts like the study of the Earth's history, the classification of minerals, and the exploration of the relationships between organisms and their environment.

If humans had been present to build log structures during the Carboniferous period (though they were not!), which plant types would have been suitable sources of logs?
Answer:
The plant types suitable during that period would be ferns, horsetails, and lycopods.
Explanation:
A geologic period and system, which covers 60 million years from the termination of the Devonian period to the start of the Permian period is known as the Carboniferous period. During the Carboniferous period, the plant life was luxuriant and extensive, mainly at the time of Pennsylvanian. It comprises ferns and fernlike trees, that is, the giant horsetails known as club mosses, calamites, or lycopods like Sigillaria and Lepidodendron.
Thus, if humans had been present to construct log structures during the Carboniferous period, then they would have used logs of ferns, horsetails, and lycopods for construction work.

Achondroplasia across the species
Genotype: 25% LL, 50% Ll, 25% ll. Phenotype: 25% Long legged, 50% Medium legged, 25% Short legged. Phenotypic ratio⇒ 1:2:1. Yes, there are 50% chances of having only medium-legged chicks. Incomplete dominance is influencing leg length.
What is incomplete dominance?
Incomplete dominance is an inheritance pattern that occurs when neither of the two involved alleles is entirely dominant over the other one. In this case, the heterozygous organism’s phenotype is different from homozygous phenotypes, and expresses as a mixture of them. This third phenotype is an intermediate between both homozygous parents.
The exposed example is a case of incomplete dominance.
Let is name the alleles as L (coding for long) and l (coding for short).
There are three possibe phenotypes,
LL ⇒ Long legsLl ⇒ Medium legsll ⇒ Short legsCross: Between two medium-legged animals
Parentals) Ll x Ll
Gametes) L l L l
Punnett square) L l
L LL Ll
l Ll ll

1/4 = 25% of the progeny is expected to be homozygous LL and express long legs2/4 = 50% of the progeny is expected to be heterozygous Ll and express medium legs1/4 = 25% of the progeny is expected to be homozygous ll and express short legsOffspring Genotype%

25% Long legged50% Medium legged25% Short leggedPhenotypic ratio⇒ 1:2:1 ⇒ 1/4 Long : 2/4 Medium : 1/4 Short
Medium-legged cabos carry both alleles, L and l, which means that during fertilization there are
25% chances that both L alleles combine producing a LL genotype, 50% chances that L and l combine producing Ll genotype,25% chances that both l alleles combine to produce ll genotype.These are expected ratios, but it does not mean the progeny will obligatory express this distribution. It depends on how alleles combine during fertilization.
If by chance, when crossing two medium-legged animals, the allele combination only occur between L and l (not L-L and not l-l), then it is possible to have only medium-legged animals.
There are 50% chances of having only medium-legged chabos.

if a person is homozygous for the delta 32 allele of the ccr5 gene, how many of the four daughter cells produced by meiosis will have the delta 32 allele?
In each of the two daughter cells, cell division resumes during telophase II, resulting in the building of four daughter cells. Each of these four daughter cells is haploid because it has 23 chromosomes. None of the four cells are identical.
The two forms of HIV resistance that exist are caused by a genetic mutation known as CCR5-delta 32. CCR5-delta 32 hampers HIV's capacity to invade resistant cells. The change influences the CCR5 co-receptor outwardly of cells to create more modest than expected and never again sit beyond the cell.
Homozygous transporters of the Delta32 change are impervious to HIV-1 disease in light of the fact that the change forestalls practical articulation of the CCR5 chemokine receptor ordinarily utilized by HIV-1 to enter CD4+ White blood cells
The CCR5 is a chemokine receptor that fills in as a co-receptor for HIV-1 connection and passage to T lymphocytes. A 32bp cancellation (∆32) in this quality is accepted to be related to protection from contamination and postponing illness movement.

Which structure fuses to form a diploid zygote during sexual reproduction?
Answer:During sexual reproduction, two haploid cells, called gametes, fuse to form a diploid cell called a zygote. In animals, the gametes are sperm and eggs, and the process by which they fuse is called fertilization. In plants, the gametes are produced by the male and female reproductive cells, called the microgametes and the megagametes, respectively, and the process is called syngamy.
During fertilization in animals, the sperm penetrates the egg, and the nuclei of the sperm and egg fuse, combining their genetic material. This forms the diploid zygote, which then undergoes cell division to form a multicellular organism.
In plants, the fusion of the microgametes and megagametes occurs at the tip of the pollen tube and the egg cell. This process is called double fertilization, which leads to the formation of a diploid zygote and a triploid cell called the endosperm, which provides nourishment for the developing seed.
In both case, sperm and egg or micro and mega gametes are the structure fusing to form diploid zygote during sexual reproduction.

the highlighted area is also referred to as the ___ border of the small intestine.
The highlighted area is also referred to as the brush border of the small intestine.
The brush border refers to a microvilli-covered surface on the apical membrane of certain epithelial cells, particularly those lining the small intestine and proximal renal tubules. The microvilli increase the surface area of the epithelial cells, which helps in the absorption of nutrients and ions from the lumen.
The brush border enzymes are located on the surface of the microvilli, where they can come into direct contact with the food material being absorbed. These enzymes are responsible for breaking down larger molecules, such as disaccharides and peptides, into smaller molecules that can be absorbed across the brush border membrane and into the bloodstream.

receptors for kisspeptin would be found on the plasma membrane of cells of the hypothalamus.
Kisspeptin receptors are found on the plasma membrane of hypothalamic cells, particularly those involved in regulating the release of gonadotropin-releasing hormone (GnRH) which controls the secretion of hormones that regulate the menstrual cycle and fertility.
Humans' release of the gonadotropin-releasing hormone is significantly aided by the protein known as kisspeptin (GnRH). Kisspeptin, a protein, and its receptor are essential for sexual development during puberty, according to endocrinologists. Kisspeptin receptors should be present in cells of the hypothalamus if kisspeptin controls the release of GnRH.
Recent research has identified kisspeptin as a crucial regulator of the mammalian reproductive axis. It is understood that kisspeptin increases the release of gonadotrophin-releasing hormone by acting centrally through the kisspeptin receptor (GnRH). In humans and other species, loss of kisspeptin signalling results in hypogonadotrophic hypogonadism. To control the production of GnRH pulses, kisspeptin interacts with other neuropeptides such neurokinin B and dynorphin. A increasing body of evidence also contends that stress and dietary status can influence kisspeptin signalling. A unique potential therapeutic target for the treatment of problems of infertility may also be kisspeptin. In healthy adults and patients with specific types of infertility, peripheral exogenous kisspeptin injection appears to promote gonadotrophin secretion.
This study seeks to offer an update on recent developments in this field and a succinct summary of what is currently known about kisspeptin as a regulator of reproductive function.
