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

Differences in the physical traits of organisms is a(n) __________________.
Differences in the physical traits of organisms is a(n) Variation.
What is variation?In biology, variation is the difference in cells, individual organisms or characters or physical traits among individuals of any species caused by either genetic makeup or an effect of environmental factors. Physical traits are those distinguishable characteristics found in organisms.
Genetic variations can emerge from variant genes known as mutations or processes where genes are rearranged as cells are getting ready to divide which is called genetic recombination. When gene activities are altered by variation, they can introduce different physical traits in organisms.

how to know if you carry the red hair gene
The test will examine each parent's DNA for evidence of the MC1R gene, which causes redheadedness. "We can... detect if an individual is a carrier of any of the three prevalent redhead variations in the gene MC1R using a simple saliva test to determine deep ancestry," stated Dr.
What causes red hair?
Red hair is a recessive hereditary feature induced by a sequence of mutations in the MC1R gene on chromosome 16. Because red hair is a recessive feature, it must be inherited from both parents.
As a result, there are significantly more persons harboring the red hair mutation than have red hair. Redheads account for around 13% of the Scottish population, with 40% carrying at least one mutation.

(a) The rate of photosynthesis will decrease because even though Hydrilla plants require less sunlight but the requirement is necessary.
(b) Three limiting factors are- Light intensity, Temperature and [tex]CO_{2}[/tex].
(c) The bubbles represent the evolution of oxygen.
What is Photosynthesis?
Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can subsequently be released through cellular respiration to power the organism's activities.
What is the Hydrilla plant?
The hardy, quickly-growing perennial herb Hydrilla has long, slender stems that can reach lengths of up to 7 meters (23 ft). The tiny, lance-shaped or oblong leaves are clearly toothed and grow in pairs or whorls of three to eight. Also, they are aquatic and always remain submerged in water, they lack stomata and use their body for photosynthesis.

Why is mitosis important 3 reasons?
Expansion and development. Mitosis is the process by which an embryo develops after a gamete from meiosis has united with another gamete to form an embryo. Cell division is essential for organism development, tissue repair, healing and regeneration, and reproduction. Asexual reproduction is a form of reproduction in which the number of chromosomes or the fusion of gametes are not altered.
Multicellular creatures depend on mitosis to reproduction of new cells for growth and to replace damaged or worn-out cells, such as skin cells. Mitosis serves as Mitosis the main asexual reproductive mechanism for a large number of single-celled organisms.

What is the correct order of steps in the cell cycle ?
The cell cycle is a four stage procedure
Gap 1, or G1 phase Synthesis, or S phase Gap 2, or G2 phase Mitosis, or M phaseThe period between cell divisions is represented by the stages G1, S, and G2, which together make up interphase. An individual cell "decides" whether or not to join the cell cycle and divide based on the stimulatory and inhibitory signals it receives.
Checkpoint signalling systems and specialised proteins are used by cells to guarantee correct cell cycle progression. DNA damage is checked for before and after S phase at checkpoints at the end of G1 and the start of G2. Similar to this, a checkpoint in mitosis makes sure that the chromosomes are properly separated in anaphase before the cell's spindle fibers are properly aligned in metaphase.
Hence, cell cycle is sequence of event in organized manner.

What is distribution of traits?
The alleles of the various genes that each individual chromosome carries are mixed and matched traits with regard to one another, resulting in a distribution of traits.
When comparing populations, differences are typically seen as variations in the frequency distributions of the states (or kinds) of a certain feature (or set of traits). As a result, if two or more populations exhibit the same trait states at the same rates, they are said to be identical. A population's variance and pattern of attributes are influenced by both genetic and environmental variables. During meiosis, chromosomes can switch sections, causing mutations brought on by environmental factors, mistakes in DNA replication, or both.
As a result, we can infer that the alleles of the numerous genes that each chromosome carries are mixed and matched traits in relation to one another, producing a distribution of traits.

What are three effects of cardiovascular endurance training?
VO2 max is increased, plasma volume expansion is stimulated, and body fat mass is decreased through cardiovascular endurance training.
The ability to undertake dynamic, large-muscle exercises for a lengthy amount of time at a moderate to high intensity is known as cardiovascular endurance (typically over 20 to 30 minutes). It gauges how well your body can expel carbon dioxide and deliver oxygen-rich blood to your organs. As a result, cardiovascular endurance serves as a reliable predictor of the health of the heart, lungs, and muscles. You can exercise and work out intensely longer if your cardiovascular endurance is higher than that of someone with lower endurance.
