Under the logistic growth model, the most important factor limiting population growth is "the carrying capacity of the environment".

The carrying capacity refers to the maximum number of individuals that a given environment can sustainably support over a long period of time, taking into account the availability of resources and other factors that influence population growth.

As a population approaches its carrying capacity, competition for resources increases, and per-capita birth and death rates may change.

However, the carrying capacity ultimately determines the maximum population size that can be sustained in the long run.

Changes in abiotic conditions, such as temperature or precipitation, can certainly affect population growth, but these factors are typically considered to be outside of the control of the population itself and are thus not typically included in models of population growth.

Its either B or C, look closely at the question and at the answers, you can narrow it down from then.

A scientist is treating rice plants with a chemical that causes mutations. The possible benefit of this treatment is transgenic plants. Hence, the correct option is B.

A mutation is a change in the DNA sequence that makes up a gene. It can result from  errors in DNA replication or exposure to mutagenic agents such as chemicals or radiation, or from spontaneous changes.

Transgenic plants are the plants that have been genetically modified to express specific traits or traits that are not found in the original species. This is done by introducing foreign DNA or chemicals that change the plant's genome. This process is called genetic engineering.

Transgenic plants have become an important tool in agriculture and biotechnology, providing new opportunities for food production, environmental protection and economic growth. Hence, the correct option is B.

A typical gamete, sometimes referred to as a sex cell, should have half as many chromosomes as a typical body cell. The third daughter cell visible in the photograph appears to have an extra chromosome, making the total number of chromosomes there 47 rather than the typical 46.

In humans, gametes are haploid cells with 23 chromosomes—one of each chromosomal pair found in diplod cells—and are hence haploid. The haploid number, commonly known as n, is used to indicate the number of chromosomes in a single pair.

Gametes are haploid because they have half as many DNA bases as from the initial diploid germ cell's chromosomes. In other words, the secondary gametes only have one set (23), whereas the germ cell had two sets (46) of chromosomes.

Answer:

A and C.

Explanation:

They are similar to the question and makes sense

When PTH mRNA is transcribed from the PTH gene and translated on ribosomes, the ribosomes are found in the cytoplasm and the translated PTH polypeptide formed is not the biologically active form of the PTH hormone.

Parathyroid hormone (PTH) is an 84-amino-acid protein hormone that helps to maintain calcium levels in extracellular fluid by mobilizing calcium from bone. When PTH mRNA is transcribed from the PTH gene and translated on ribosomes, the ribosomes are found in the cytoplasm and the translated PTH polypeptide formed is not the biologically active form of the PTH hormone.

This polypeptide is cleaved in the Golgi apparatus, and the biologically active hormone is then secreted from the parathyroid gland cells into the bloodstream. The biologically active form of the PTH hormone contains the first 34 amino acids, known as PTH(1-34), which has a half-life of about 4 minutes. The remainder of the PTH molecule is cleaved rapidly, with PTH(7-84) being the predominant form of circulating PTH, and having little biological activity.

Step 1.

Write down the experiment data.

- tube containing water;

- alodea (photosynthetic organism);

- 10 g of sodium bicarbonate;

- light source.

Step 2.

Why bubbles are formed on the leaves of the alodea?

The experiment have all the condictions for photosynthesis, since it provides: water (that is in the tube), CO2 (because of the dissolved sodium bicarbonate), light (because of the string light source). Therefore the most ogical explanation for Alice experiment results is: the bubbles formed as the elodea plant releases oxygen from the elodea leaves, that because with all the elements in the experiment the plant can do a normal photosynthetic process that way realing oxygen in the tube and forming bubbles of "air".

The mass of the wax after the melting would still be exactly 50 g

A cornerstone of physics and chemistry is the law of conservation of mass, commonly referred to as the principle of mass conservation. It asserts that mass cannot be created or removed in a closed system.

In other words, the total mass of a closed system remains constant over time, regardless of any physical or chemical changes that may occur within the system.

Since the mass of the wax would not change, it would be right to say that by this law, the melted wax would stull weigh 50g

Speed ​​up or slow down the cell cycle are functions of external regulators of the cell cycle.

The regulation of cell proliferation, growth and DNA synthesis are controlled by the regulatory machinery of the cell cycle.

Cell cycle progression is activated directly by a series of heterodimers formed by cyclins and cyclin-dependent kinases (CDKs).

Therefore, we can conclude that speed ​​up or slow down the cell cycle are functions of external regulators of the cell cycle.

Lactic acid fermentation is an anaerobic respiration process that occurs in animals.

Anaerobic respiration is the process by which cells break down sugars to produce energy in the absence of oxygen. In contrast, aerobic respiration, which uses oxygen to produce energy, is a highly efficient process. Because of its high electron affinity, molecular oxygen is the most efficient electron acceptor for respiration. Some organisms, however, have evolved to use other final electron acceptors and, as a result, can respire without oxygen.

The effects of picolinic acid, a byproduct of tryptophan breakdown, on mouse peritoneal macrophage activation (M phi). Picolinic acid works in tandem with IFN-gamma to activate M phi in C57BL/6 mice.

Furthermore, M phi from C3H/HeJ and C3H/HeN mice that are not cytotoxic in response to IFN-gamma alone might be fully activated by picolinate plus IFN-gamma. These findings suggest that picolinic acid is a powerful costimulator of M phi activation that acts as a secondary signal. Given that activation of cytotoxic M phi correlates with particular alterations in ribosomal RNA (rRNA), we studied whether picolinic acid could influence M phi RNA metabolism.

Picolinic acid decreased total M phi RNA synthesis, increased the accumulation of newly synthesised 28S rRNA, and increased the steady-state levels of rRNA precursors (pre-rRNA). These RNA metabolic modifications were similar to those previously observed in murine M phi that had been activated in vitro or in vivo to express tumoricidal function. These findings show that picolinic acid is a powerful, biologic M phi second signal, that changes in rRNA are directly related to the expression of tumoricidal activity, and that picolinic acid has an autocrine effect.

The fish will not survive because the freshwater would be hypotonic to the body of the fish and as such, excess water would enter its body which will lead to its death. The cells that make up the body of the fish will take-in excess water and lyse, leading to the death of the fish itself.

Answer:

0.417 m/s

Explanation:

Speed is the change of rate in position (distance traveled) by time, it represents how fast or slow something or someone is moving. It is a scalar measure since it does not take into account direction, if direction was taken into account the resulting vectorial measure would be called velocity.

So in order to calculate the speed we would divide the distance moved by the time taken to move:

1500m/3600s = 0.416666 m/s

note that the units come given by the units of the numerator and denominator meters per second.

Answer:Diabetes is the most common cause of kidney disease

Hope this helps..

Answer: Diabetes and Yellow fever

Diabetic kidneys cannot process as much sugar as a healthy kidney. Some diabetes is temporary, when a mother is pregnant, it can cause them to have diabetes. (NOTE: A pregnant woman should always have a diabetes test while they are carrying) Pregnancy diabetes will go away shortly after the child is born.

Yellow fever is much more harmful than diabetes, and can sometimes, without proper health care, be fatal. A kidney infected with yellow fever will not filter out all the bacteria and waste properly, making the outside of people and animals have a yellow tint, which is most visible in the eye. Yellow fever is passed on from mosquitos.

The correct statement is: They do not assort independently and do not produce Mendelian ratios for crosses tracking two or more genes.

Linked genes are genes that are located close to each other on the same chromosome.

Unlike genes that are located on different chromosomes, linked genes tend to be inherited together as a result of their physical proximity. This means that they do not assort independently during meiosis, breaking the principle of independent assortment proposed by Gregor Mendel.

When two or more genes are linked, their inheritance does not follow the expected Mendelian ratios observed for unlinked genes.

In Mendelian genetics, genes located on different chromosomes segregate independently into gametes and produce predictable ratios in offspring.

However, linked genes tend to stay together and are less likely to undergo recombination, resulting in deviations from Mendelian ratios in crosses involving multiple linked genes.

The phenomenon of genetic linkage and its impact on inheritance was one of the key discoveries in genetics that provided evidence for the existence of chromosomes and helped develop the concept of genetic mapping.

The reduction in chromosome number occurs during meiosis I.

Chromosomes are long molecules of DNA that contain some or all of an organism's genetic material. In most chromosomes, very long, thin strands of DNA are coated with packaging proteins. In eukaryotic cells, the histones are the most important of these proteins.

Within the nucleus of all cells, DNA molecules are packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly wrapped many times around proteins called histones that support its structure.

Another type of cell division, meiosis, ensures that humans have the same number of chromosomes from generation to generation. This is a two-step process in which the number of chromosomes is halved from 46 to 23 to form sperm and eggs.
