Answer:
The correct answer would be B) enclosed in a protein capsule
Almost all living cells contain DNA as their genetic material. DNA control and coordinates the function of the cell. The two cells also must contain the DNA.
Cellular respiration refers to the set of biochemical reactions by which the cell generates ATP or energy. All the living cells produce energy through cellular respiration, however, they may utilize the aerobic or anaerobic form of respiration.
A ribosome is found in all the living cells including animal cells, plants, bacteria et cetera. They form the site for protein synthesis in all the cells.
The protein capsule is not a universal feature of all living cells. Thus, it may be present in one cell type and absent in another cell type.
Plants need water
and the second option is true
Answer:
K-strategists
Explanation:
Reproductive pattern in organisms can be typically categorised into two:
1. K- Strategy
2. R- Strategy
K-strategists are organisms that lives in very stable environments and gives birth to fewer organisms. Most of these organisms reproduce close the carrying capacity of their habitat. They offer support and protection to their progeny to the points where they become indepedent. The mortality rate is very low in such organisms and so is the birth rate too.
R-strategists are organisms whose main aim is to populate and dominate an environment. They reproduce exponentially and offers no life support to their progeny in their early developmental stage. They often occupy unstable and highly unpredictable environments. Most R organisms have a very low and short life expectancy. Since they produce more offspring and they live under adverse environments, mortality rate is high.
Examples of K-strategists are elephants and man
Examples of R-stategists are grasses and microbes.
The correct answer is that the following is true concerning sources of water pollution is option a. Mine wastes and heavy metals become water pollution through stormwater runoff.
Mine wastes and heavy metals become water pollution through stormwater runoff. As water contaminates by producing coppers, sulfate, sodium as the toxic elements contaminating the water. The chemicals are released from mining activities by contaminating soil, air, by causing pollution.
<h3>What are sources of water pollution?</h3>
The sources of water pollution are :
- mining
- industrial wastes.
- marine dumping
- burning of fossils
- chemical fertilizers.
Hence concluded that water pollution can cause be caused by Mine wastes and heavy metals becoming water pollution through stormwater runoff.
