Population growth rate for Zambia is 0.8 % when CBR= 2.9%, Immigration = 1%,CDR = 2.1%, Emigration = 1% are as given above.

The crude birth rate is the number of live births per 1,000 of the population at the midyear census. long explanation The crude birth rate is the number of live births per 1,000 of the expected population at the midyear mark.

Given data;

CBR= 2.9%, Immigration = 1%,

CDR = 2.1%, Emigration = 1%

Now to find the Population Growth Rate use the given formula;

(CBR + Immigration) - (CDR + Emigration) = Population Growth Rate

Population Growth Rate= (CBR + Immigration) - (CDR + Emigration)

the current population of Zambia =18.92 million

now

CBR= 2.9% of 18.92 million=548680

CDR = 2.1% of 18.92 million=397320

Immigration = 1% of 18.92 million=189200

Emigration = 1% of 18.92 million=189200

now putting the values on eq.

Population Growth Rate= (CBR + Immigration) - (CDR + Emigration)

Population Growth Rate= (548680  +189200)-(397320 + 189200 )

Population Growth Rate=151360 *100/18.92 million

Population Growth Rate=0.8%

Answer: parasitism can help shape biodiversity by exerting selective pressure on host populations and by contributing to the diversity of parasitic organisms themselves.

Explanation: Parasitism is a form of symbiotic relationship where one organism, the parasite, benefits while the other, the host, is harmed. Parasites can have a significant impact on the biodiversity of an ecosystem by selecting and shaping the characteristics of their host species.

Parasites have evolved to infect specific hosts, which means that their survival and reproduction are tied to the existence of their host. As a result, parasites can exert selective pressure on the host population, favoring certain traits and characteristics that make the hosts more resistant or susceptible to infection.

This selective pressure can lead to evolutionary changes in the host population, which can lead to increased genetic diversity. For example, if a parasite infects a population of fish and selects for fish that have more effective immune systems, then those fish will be more likely to survive and reproduce, passing on their advantageous traits to their offspring. This can ultimately lead to the development of new species.

Furthermore, parasites themselves can be incredibly diverse. Studies have shown that parasites can account for a significant percentage of the total biodiversity in an ecosystem. By infecting different hosts and adapting to different environments, parasites can influence the evolution of their hosts and contribute to overall biodiversity.

Answer:

Parasitism, in common with competition, facilitation, and predation, could regulate BD-EF relationships. Parasitism affects host phenotypes, including changes to host morphology, behavior, and physiology, which might increase intra- and interspecific functional diversity.

The process represented by 1 and 2 could be meiosis which is a type of cell division. The process represented by 3 could be fertilization which is the fusion of gametes to form a zygote.

The process of cell division called meiosis, that produces gametes with half the number of chromosomes as the parent cell is responsible for producing gametes. The genetic information provided by a parent to its offspring is determined by heredity and varies from one individual to another as do other genetically determined traits.

The life cycle of humans is divided into different stages. The sperm from the adult male human and the egg from the adult female human form a zygote inside the uterus. This zygote then undergoes mitosis to form an embryo. The embryo then develops into a fetus which is born after around nine months.

Answer:

200 to 500 milliseconds

Explanation:

Attentional blink is a phenomenon that puts time-related limitations to the ability to utilize visual attention. When an individual must identify two visual stimuli presented one after another, the accuracy is very poor for the second stimulus if it occurs within 200 to 500 milliseconds of the first stimulus.

So, in our question, the gap is filled by 200 to 500 milliseconds.

Phagocytes are a type of immune cells that specialize in engulfing and digesting foreign particles, such as bacteria, viruses, and cellular debris. The two phagocytes are Neutrophils and Macrophages.

Neutrophils are a type of white blood cell and are the most abundant phagocytes in the bloodstream. They are quick to respond to infections and are often the first immune cells to arrive at the site of an infection. Neutrophils engulf and destroy pathogens by a process called phagocytosis.

Macrophages are a type of white blood cell that is present in various tissues and organs of the body. They are highly specialized phagocytes and play a crucial role in engulfing and eliminating foreign substances. Macrophages not only participate in immune responses but also contribute to tissue repair and maintenance.

The correct answer is Neutrophils and Macrophages.

Answer:

Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air.

Answer:

The sun's radiation hits the ground on Earth which results in heating it. Now since the ground is heated the temperature is high so it rises up due to conduction. This is how heat energy is released into the atmosphere.

False, ribosomes are not involved in transport of things around the cell.

What are ribosomes?

Organelle involved in transportation: ENDOPLASMIC RETICULUM

Similar to how a city's road network enables mobility within it, the endoplasmic reticulum is a network of tube-like passageways via which proteins from the ribosomes can be transported.

Endoplasmic reticulum is another name for it. There are two types: RER and SER. Rough ER and Smooth ER are abbreviations for respectively. Ribosomes are affixed to rough ER, aiding in the synthesis of proteins. Cells use ERs for a variety of purposes. One of their main jobs is to serve as a transport route. The endoplasmic reticulum membrane is used to transport secretory proteins, primarily glycoproteins.

Hence, endoplasmic reticulum is involved in transport and not the ribosomes
