Plants contain meristems whose major function is to:.
Answer:
Growth in length
Explanation:
Meristems are regions of active cell division within a plant. In general there are two types of meristems: apical meristems and lateral meristems. Apical meristems are located at the tip of the shoot and the root, as well as at the tips of their branches. These meristems occur in all plants and are responsible for growth in length.
What important role does water play in the function that needs to be performed by the kidneys
Answer:
Water helps the kidneys remove waste from your blood through urine. Water also helps keep blood vessels open, which lets blood flow through easier, letting the blood remove its waste through the kidney more efficiently.
Explanation:
Answer:
It helps in Osmoregulation and removal of excess liquid from the body.
Explanation:
It regulates fluid balance by excreting excess amount of water as urine while retaining the necessary amount of water in the body that is essential for living.
Osmoregulation - the process of maintaining salt and water/osmotic balance across membranes within the body.
The fluids inside and surrounding cells are composed of water, electrolytes, and non-electrolytes.
A person with a recessive allele for colour blind may not be colur blind explain
Answer:
color blindness is inherited as a recessive trait on the X chromosome. This is known in genetics as X-linked recessive inheritance. As a result, the condition tends to affect males more often than females
Explanation:
A cement factory emits 900 kilograms of CO2 to produce 1,000 kilograms of cement. A fully grown tree removes six kilograms of CO2 per day from the air. One acre of land can support 200 mature trees.
A company builds a factory that will produce 100,000 kilograms of cement. To make the factory carbon neutral, the owners need to grow
trees over an area of land measuring
acres.
Answer: To make the factory carbon neutral, the owners need to grow 15000 trees over an area of land measuring 75 acres
Explanation:
From the information;
900 kg CO2 = 1000 kg Cement
1 tree = 6 kg CO2
1 acre = 200 trees
100000 kg Cement will require;
=(900 × 100000)/1000
= 90,000 kg of CO2
But 1 tree = 6 kg of CO2
Number of trees = 90,000/6
= 15,000 trees
But, 1 acre = 200 trees
Number of acres = 15,000/200
= 75 acres of land
Therefore;
To make the factory carbon neutral, the owners need to grow 15000 trees over an area of land measuring 75 acres
Answer: a and d
Explanation:
Approximately
% of the available energy is passed from organisms at one trophic level to organisms at the next trophic level.
Approximately 10% of the available energy is passed from organisms at one trophic level to organisms at the next trophic level. This is known as the 10% rule or the 10% energy transfer efficiency.
What is 10% rule?Energy flows through trophic levels in an ecosystem starting with producers (plants or algae) that convert sunlight into chemical energy through photosynthesis. When herbivores consume these producers, only a fraction of the energy stored in the plants is assimilated into their bodies, while the rest is lost as waste or used for metabolic processes like respiration. This assimilated energy becomes available to the next trophic level.
As energy moves up the food chain, similar inefficiencies occur at each level. Carnivores that consume herbivores receive only about 10% of the energy stored in their prey. This pattern continues as energy is transferred to higher-level predators.
The low energy transfer efficiency can be attributed to several factors. First, organisms expend energy for basic metabolic processes, such as respiration, movement, and growth, which reduces the energy available for transfer. Second, energy is lost as heat during these metabolic processes. Additionally, not all parts of an organism are consumed or digested by predators, resulting in energy losses through waste.

Study the cladogram. Which two organisms have dry skin? gorilla and shark shark and lizard lizard and tiger tiger and lamprey.
Answer:
It's C.
Explanation:
I chose B but I got it wrong. Since lizards obviously have dry skin, the other option with lizards is C. And you can also see in the cladogram that above "dry skin" is lizards and tigers.
So it's C.
The relationship between the two organisms is represented by a cladogram. Here, dry skin is seen in lizard and tiger. Thus, option c is correct.
What is a cladogram?Cladogram is based on the evolutionary relationship between the organisms and how closely they are related to each other. It is expressed in the form of branching diagram.
In cladograms, the morphological features are included. However, advanced cladograms can be constructed using DNA or RNA sequencing.
Cladograms are useful tools for studying evolution as they are represented through simple diagram. The advantage of using cladogram is that it includes only the pure characters. No derived characters are taken into account.
Thus, cladograms are important in determining the evolutionary relations amongst the taxonomic groups.

What are Chromosomes?A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code. The very long, thin DNA fibres in most chromosomes are covered with packing proteins; in eukaryotic cells, the histones are the most significant of these proteins.
The highest possible level of DNA and protein organisation is seen in chromosomes. Chromosomes' primary job is to carry DNA and pass genetic material from one generation to the next. Cell division involves the critical function of chromosomes. They guard against tangles and damage to the DNA.
