Which statement best describes Earth's human carrying capacity?
A: It is a fixed number that we will soon exceed.
B: It is increasing due to improved technology and medicine.
C: It is decreasing due to increasing population.
D: It is decreasing due to decreasing death rates.
The statement that best describes Earth's human carrying capacity that it is increasing due to improved technology and medicine. The correct option is B.
What is carrying capacity?Carrying capacity is the amount of persons the individual may experience over a lengthy amount of time and density affects the overall population.
Food, habitat, moisture as well as other necessities found in the environment determine carrying capacity.
Carrying capacity is defined as the average population size of a species in a given habitat.
Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these needs are not met, the population will decrease until the resource rebounds.
The best description of Earth's human carrying capacity is that it is increasing as a result of improved technology and medicine.
Carrying capacity is defined as the maximum number of individuals of a population that the environment can support.
Thus, the correct option is B.

Mitosis makes.....
A. cell phones
B. identical body cells
C. sperm and egg cells
B. identical body cells
hope it is helpful to you
Answer:
B. identical body cells
Explanation:
Mitosis produces new cells, and replaces cells that are old, lost or damaged. In mitosis a cell divides to form two identical daughter cells. ... Mitosis separates these chromatids, so that each new cell has a copy of every chromosome.
In non-muscle cells, a small increase in the cytosolic concentration of Ca2 can have a dramatic effect on several physiological processes. The presence of a specific protein in the cytosol, however, activates a Ca2 ATPase that serves to return these elevated cytosolic Ca2 levels back to basal levels, thereby maintaining the cell's normal physiology. Which protein is directly involved in activating this Ca2 ATPase
Answer:
calmodulin
Explanation:
The calcium-modulated protein (calmodulin) is a calcium-binding receptor protein that modulates contractile proteins (i.e., actin and myosin proteins) of the skeletal muscle and non-muscle cells (e.g., platelets). Calmodulin binds to calcium ions (Ca2+) and subsequently activates a number of Ca2+ dependent enzymes (e.g., kinases or phosphatases), which finally activate/deactivate proteins in the calcium signal transduction pathway. Ca2+-ATPase pumps in the membranes of eukaryotic cells release Ca2+ from the cytoplasm and they are autoinhibited by low Ca2+ levels, while calmodulin-binding releases this autoinhibition and thus activates the pumps. In non-muscle cells such as platelets, calmodulin also mediates Ca2+ control of actin-myosin interaction by phosphorylation of the myosin light chain (MLC).

Anthropologist: In an experiment, two groups of undergraduates were taught how to create one of the types of stone tools that the Neanderthals made in prehistoric times. One group was taught using both demonstrations and elaborate verbal explanations, whereas the other group learned by silent example alone. The two groups showed a significant difference neither in the speed with which they acquired the toolmaking skills nor in the level of proficiency they reached. This shows that Neanderthals could just as well have created their sophisticated tools even if they had no language
Which one of the following, if true, most weakens the anthropologist's argument?
(A) Apart from the sophistication of their stone tools, there is a great deal of evidence suggesting that Neanderthals possessed some form of language.
(B) The students who were taught with verbal explanations were allowed to discuss the toolmaking techniques among themselves, whereas the students who learned by silent example were not.
(C) The tools that the undergraduates were taught to make were much simpler and easier to make than most types of tools created by Neanderthals.
(D) The instructor who taught the group of students who learned by silent example alone was much less proficient at making the stone tools than was the instructor who taught the other group of students.
(E) The tools created by Neanderthals were much less sophisticated than the tools created by anatomically modem humans who almost certainly possessed language and lived at the same time as the Neanderthals.
Answer:
A
Explanation:
The point of this arguement is that with or without speaking they were able to make the same sophisticated and complex tools, if it is true that both had a language that would mean the silent people would have no point and that both types of humans had the same initial factors.

How does polyploidy allow speciation to occur in a single generation? Polyploid offspring produce gametes earlier in the mating season than than their diploid parents, causing reproductive isolation between the two generations. Polyploid offspring produce smaller gametes that disperse farther than the gametes of diploid parents, causing geographic isolation between the two generations. Physiological differences between polyploid offspring and their diploid parents allow them to thrive in different environments, causing geographic isolation between the two generations. Genomic differences between polyploid offspring and their diploid parents prevent them from successfully interbreeding, causing reproductive isolation between the two generations.
Answer:
Genomic differences between polyploid offspring and their diploid parents prevent them from successfully interbreeding, causing reproductive isolation between the two generations.
Explanation:
Speciation is an ecological and biological process through which new species are formed due to isolation.
In plants, polypoidy involves the possession of two complete sets of chromosomes and it leads to the origin of new species. Also, the two sets of chromosomes comprises of triploidy (69 chromosomes) and tetraploidy (92 chromosomes).
As a result of the genomic differences between polyploid offspring and their diploid parents, this usually prevent them from successfully interbreeding and consequently causing reproductive isolation between the two generations.

where does pollination takes place in the flower
Answer:
To be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination.

Adults produce gametes through a type of cellular reproduction called mitosis. The process of a sperm cell and an egg cell fusing together is called fertilizationand produces a zygote. As a zygote undergoes rapid cell division to develop into an embryo, fetus, and eventually baby, the type of cellular reproduction being used is . As a baby grows into an adult, the type of cellular reproduction used is mitosis.
Answer:
Mitosis.
Explanation:
Mitosis is the type of cellular reproduction which is used in order to develop an embryo, fetus, and eventually baby. In mitosis type of cell division, the parent and mature cells divides into two daughter cell. This type of cell division occurs in somatic or body cells whereas meiosis type of cell division occurs in the sex cells which produces four daughter cells from a single parent cell.

HELP! What evidence indicates that many psychological disorders, such as schizophrenia and developmental
disorders, are biologically and not environmentally based?
Answer:
Schizophrenia and developmental disorders are traced genetically, and the gene will be found in the biological parents of the person with either schizophrenia or developmental disorders.
Explanation:
Although Schizophrenia can be triggered by environmental factors, or the 'nurture' of childhood development, a person who is not predisposed genetically to schizophrenia will not get the psychological disorder. The same is to be said about developmental disorders such as Autism and ADHD, it is hereditary.
For citation of evidence, I recommend talking about prenatal development, and how toxic substances can alter the development of a fetus, which is proven to lead to some developmental disorders, such as Fetal Alcohol Syndrome.
Answer:
Schizophrenia and developmental disorders are genetically connected, and the gene will be found in either the individual's biological parents or the person suffering from schizophrenia or developmental abnormalities.

In humans, brown eyes are dominant to
blue eyes. What is the probability
that two heterozygous brown-eyed
parents will have a child with blue
eyes?
J. 25%
K. 50%
L. 75%
M. 100%
Answer:
j
Explanation:
since brown eyes are more dominant than blue eyes chances of it is 3/4
Answer:
The answer is J. 25%.
Explanation:
In this problem, we know brown eyes are dominant to blue eyes. We can let the dominant allele for brown eyes be represented by "B" and the recessive allele for blue eyes be represented by "b". Since it is given that both parents are heterozygous, we know that they must have the genotype Bb.
When two Bb individuals are crossed, the offspring will be 1 BB : 2 Bb : 1 bb, or 3 brown : 1 blue ratio. Therefore, 1/4 of the offspring will have blue eyes, which represents 25%. Thus, the correct answer is choice J, 25%.
