Why does population growth slow as size increases in the logistic model?
A : due to density-dependent factors
B : due to density-independent factors
C : due to a decrease in death rate
D : due to an increase in birth rate
Answer:
due to densinty dependent factors
Explanation:
because it determining energy requirement in human being
Population growth slow as size increases in the logistic model A : due to density-dependent factors is correct option.
In the logistic model of population growth, the slowdown in population growth as the population size increases is primarily attributed to density-dependent factors. Density-dependent factors are those that have a stronger impact on a population when its density (number of individuals per unit area) is higher. As a population grows and becomes more dense, competition for resources (such as food, space, and mates) intensifies, and factors like disease transmission and predation become more significant.
These density-dependent factors can lead to a decrease in birth rates, an increase in death rates, or both, which ultimately results in the population growth rate slowing down and eventually stabilizing at its carrying capacity (the maximum sustainable population size for a given environment). This pattern is characteristic of the logistic growth model, which describes a more realistic and sustainable form of population growth compared to the exponential growth model.

What is the role of pitutary gland in puberity
Answer:
Puberty has begun. The trigger for puberty in both boys and girls is the production of 'gonadotrophin releasing hormone' (GnRH) from a part of the brain called the hypothalamus. This hormone stimulates the pituitary gland to release two hormones, Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH).
Explanation:

Describe the purpose of mitosis.
2. Describe what is happening in each stage and what each stage looks like:
Prophase
Prometaphase
Metaphase
Anaphase
Telophase
Cytokinesis
Answer:
To acquire growth and to replace worn out and defected cells.
Explanation:
The main purpose of mitosis is to acquire growth and to replace worn out and defected cells.
In prophase, the chromatin condenses which is present in the nucleus of the cell.
Prometaphase is the stage where the nuclear membrane breaks apart into numerous "membrane vesicles".
Metaphase is the phase where all the genetic material is condensing into chromosomes.
Anaphase is the stage in which chromosomes are pulled by the spindle fibers to opposite poles of the cell.
In Telophase, the cell is nearly dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place.
Cytokinesis is the process which divides the cytoplasm of a parental cell into two daughter cells.

Cells control or regulate the flux through metabolic pathways by means of I. allosteric control of enzymes. II. covalent modification of enzymes. III. genetic control of the concentrations of enzymes. IV. genetic expression of allosteric regulators.
Answer:
I, II, III
Explanation:
Allosteric regulation is a common mechanism of regulation of enzyme activity, which generally involves key enzymes in metabolic pathways. Allosteric modulation occurs when a substance/molecule called 'allosteric regulator' binds to an enzyme at a site other than the enzyme's active site, thereby triggering a conformational change in the enzyme and thus affecting its activity. Moreover, covalent modifications such as phosphorylation, acetylation, methylation, etc, are also involved in the regulation of enzymatic activity in metabolic pathways. For example, phosphorylation is a type of reversible covalent modification of proteins consisting of the addition of phosphate groups at specific amino acid residues (i.e., serine, threonine, and tyrosine) by specific enzymes known as protein kinases. Phosphorylation alters the three-dimensional (3D) structure of proteins, thereby turning the substrate or cellular pathway to active and/or inactive. Finally, both transcriptional and post-transcriptional mechanisms are also able to control the expression of enzymes involved in signaling pathways. Transcriptional mechanisms are capable of limiting the amount of mRNA that is produced from a given gene (in this case, an enzyme encoding gene), whereas post-transcriptional mechanisms such as, for example, RNA interference pathways, control the translation of messenger RNA (mRNA) molecules into proteins.

If a person develops chronic lymphocytic leukemia, what leukocytes may be involved and how mature are they in the bloodstream? Common symptoms of all types of leukemia are caused not only by the poor functioning of leukocytes, but also by the loss of erythrocytes and platelets. These formed elements have a reduction in their number because the tissue that normally produces them is crowded out by the uncontrolled growth of the leukocyte-producing tissue. For each symptom below, state whether leukocytes, erythrocytes, or platelets are involved.
anemia
easy bleeding
repeated infections
enlarged lymph nodes
shortness of breath
excessive bruising
Answer:
The correct answer is -
anemia- erythrocytes
easy bleeding- platelets
Repeated infections - leucocytes
enlarged lymph nodes- leucocytes
shortness of breath- erythrocytes
excessive bruising- Platelets
Explanation:
Cancer of the lymphocytes is chronic lymphocytic leukemia (CLL). Lymphocytes are a type of white blood cell involved in the body's immune system.
Platelets are tiny blood cell fragments that help your body form clots to stop bleeding. The platelets then rush to the site of damage and form a plug, or clot, to repair the damage.
Erythrocytes are red blood cells that travel in the blood. They carry oxygen from the lungs to the body and bring carbon dioxide back to the lungs to be expelled.
Leucocytes- White blood cells (also called leukocytes or leucocytes and abbreviated as WBCs) are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.
functions of insulin
Answer:
Insulin helps control blood glucose levels by signaling the liver and muscle and fat cells to take in glucose from the blood. Insulin therefore helps cells to take in glucose to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.

Describe fluid exchange between capillaries and the interstitial fluid. Be sure to discuss the forces (pressure) that moves the fluid and the direction in which fluid moves. (4 points) In one to three sentences, describe the role of lymphatic system in this fluid exchange. (3 points) g
Answer:
Capillary exchange is the exchange of fluid from the capillaries into the interstitial fluid and vice versa. Diffusion, transcytosis, and bulk flow are three mechanisms that facilitate capillary exchange.
The blood plasma or interstitial fluid exerts a pressure of the fluid on the capillary walls known as Hydrostatic pressure. Osmotic pressure is a pressure exerted by proteins either in the blood plasma or interstitial fluid called oncotic pressure.
Lymphatic capillaries gather lymphatic fluid and regulate the pressure of interstitial fluid due to the forces of hydrostatic or oncotic pressure. An essential role of the lymphatic system is to return the fluid to the blood.

Given the range of current speeds shown on the graph above, would deposition ever be possible for clay (0.001 mm) or silt (0.01mm) particles?
Answer yes or no and explain your answer.
Answer:
Yes.
Explanation:
Yes, deposition can be possible for clay (0.001 mm) and silt (0.01mm) particles when the agent that carry its load is absent in that region such as wind. Wind is the agent that moves clay and silt particles with it so if there is high wind in a specific region, no deposition will occur while on the other hand, those areas where wind is not present, deposition will definitely occurs so we can say that deposition depends on the presence and absence of wind.
During transcription, RNA polymerase synthesizes RNA from a DNA template with the help of accessory proteins.
a. True
b. False
Answer:
The correct answer is a. True
Explanation:
The information to produce a protein is coded in the cells in deoxyribonucleic acid (DNA). Transcription is the process in which a DNA sequence is copied into a ribonucleic acid (RNA) sequence. This RNA sequence is a messenger RNA (mRNA) because it will be then translated into a functional protein. For this, the DNA sequence is read and an RNA strand is synthesized by an RNA polymerase (an enzyme that synthesizes RNA molecules from a DNA template). During the process participate other proteins, such as DNA binding proteins, activators, coactivators, etc. (accessory proteins).

Which of the following combinations of phylum and description is correct? (and why?)
a) Nematoda − roundworms, internal skeleton
b) Porifera − gastrovascular cavity, coelom
c) Echinodermata - radial symmetry as a larva, coelom
d) Platyhelminthes − flatworms, gastrovascular cavity, no body cavity
The phylum and description that is correct among the options is Platyhelminthes − flatworms, gastrovascular cavity, no body cavity
Flatworms belongs to the phylum platyhelminthes. They are said to have no true body cavity, but they do have bilateral symmetry. For the lack of a body cavity, it is called acoelomates. They also have an incomplete digestive system. That is, the digestive tract has only one openingsFrom the above we can therefore say that Option d is the correct option that gives the true description of the phylum platyhelminthes

8. Which of the following statements about plasma membranes is INCORRECT?
A. They are composed of phospholipids.
B. They have both integral and peripheral proteins.
C. They are relatively rigid structures.
D. They function to separate the extracellular and intracellular environment.
CONT
st?
Answer:
C. They are relatively rigid structures.
Explanation:
The plasma membrane is a semipermeable lipid bilayer mainly composed of amphipathic phospholipids, which acts as a barrier to separate the cytoplasm from the extracellular environment. This barrier is considered a fluid combination of proteins, lipids and carbohydrates. The fluid mosaic model states that the plasma membrane is a mosaic of lipids (especially phospholipids and cholesterol), as well as proteins and carbohydrates (glycolipids and glycoproteins) that are constantly moving. This fluidity alters the rotation and diffusion of proteins and other components within the plasma membrane, thereby affecting their functions. Membrane fluidity has been experimentally demonstrated by a variety of techniques. (e.g., X-ray diffraction, labeling techniques, calorimetry, etc).
In this scenario you want to test if the evolution of a food preference may reinforce reproductive isolation. You know that you want to measure if golden rain tree bugs and balloon vine bugs prefer fruits from either host plant. Please write a hypothesis based on this.
Answer:
It is given and we know that if balloon vine bugs and golden rain tree bugs prefer fruits from either host plant. Then the change in the food preference leads to reproductive isolation which is sympatric isolation
There is the ongoing rapid evolution of bugs in relation to the seed defense structures of their host. Rapid evolution in bug populations that feed on recently introduced sapinds is grounded with an ancestral pattern of coevolution between the bugs and the defenses of sapinds.
