Answer : He needs to use a larger sample size to improve his experiment.
Explanation : As Johannes wants to know whether soil, water, or both are needed for plant growth. He chooses to conduct experiments on a willow tree for five years. To get the improvement in his experimental methods he can choose a larger size of the sample and test its results. As larger size will allow him to gauge accurately on the smaller factors and results will be more reliable. Larger sampling will ensure the homogeneity of the test sample, which will yield better and reliable results.
Johanneswants to know whether soil, water, or both are needed for plantgrowth. He chooses to conduct experiments on a willow tree for fiveyears to answer his question. His experimental methods can be changedby testing more factors in the environment. This will improve hisexperiment.
Ihope it helps, Regards.
Legumes, a type of plant, require Rhizobia, a type of soil bacteria, to survive since these organisms fix nitrogen during photosynthesis. Rhizobia use the legumes for food. If Rhizobia suddenly became extinct the legumes become extinct too because for the growth of legumes rhizobia is required and if they are extinct than legumes also extincted.
A legume is a plant from the family of fabaceae, they are basically pulses that are the rich source of protein. Legumes are grown agriculturally, primarily for human consumption, for living and forage and silage.
Legumes are chickpeas, peanuts, green peas, black beans, kidney beans, navy beans and lima beans.
Legumes are plants refers to a plant from the family fabaceae that would include leaves, stems, and pods.
Rhizobium is a gram- negative soil bacteria that fix nitrogen in the soil and they are also known as nitrogen fixing bacteria and they help to fix nitrogen of soil during the process of photosynthesis.
The rhizobium is from class alphaproteobacteria, Genus rhizobium and order hyphomicrobiales, phylum pseudomonadota and domain bacteria.
Therefore,Legumes, a type of plant, require Rhizobia, a type of soil bacteria, to survive since these organisms fix nitrogen during photosynthesis. Rhizobia use the legumes for food. If Rhizobia suddenly became extinct the legumes become extinct too because for the growth of legumes rhizobia is required and if they are extinct than legumes also extincted.

The answer is: the legumes will extinct, too.
It is known that plants cannot directly use atmospheric nitrogen. But, some legumes have a symbiotic relationship with bacteria that live in their root system. These bacteria are called Rhizobia and have the ability of nitrogen-fixation. In the root nodules, they use atmospheric nitrogen to convert it into ammonia, and later to ammonium, which can be used by plants. When legumes die, nitrogen from their remaining is released back to the soil where it is available to the other plants.
So, if Rhizobia suddenly became extinct, the symbiotic relationship between will be interrupted. The legumes will not be able to use atmospheric nitrogen without the help of Rhizobia, and eventually, they will extinct, too.
Answer:
Gonorrhea
EDG 2021
Explanation:
Painful urination associated with burning and a yellowish discharge is associated with
B) 25%
C) 40%
D) 50%
Answer: The correct answer is 25%.
Black color (B) of horse is a dominant trait over brown (b) color, which is a recessive trait. As we know that dominant gene masks the expression of recessive gene, therefore brown horse color will only be produced in the genpotype bb.
On the other hand, there are two possible genotypes for black horse color that is BB and Bb.
As per the question, parental genotypes are Bb and Bb. When they are crossed, they will produce 25 % foal with brown color (bb).
Refer punnett square.
b. haploid.
c. monoploid.
d. polyploid.
Answer:
The correct answer is a. diploid.
Explanation:
Gametes are haploid entity which contains one genome or one complete set of chromosome a particular organisms. Gametes are represented by (n) and are produce as a result of meiosis in the germ cells during gametogenesis. Fusion or fertilization of a male and a female gamete results into one celled structure called zygote. The zygote receives two genomes one each from a male gamete and a female gametes. Thus, a zygote contains two sets of chromosomes. ( n+n) = 2n or diploid.
(B) The a allele is recessive lethal.
(C) The alleles assort independently.
(D) The gametes combine at random.
(E) The probability that a given gamete will receive allele A is one-hal
