Explain briefly four
why, peasant
farmers find it diffcult to get
farm credit
Answer:
The peasant farmers operate mainly in the rural environment of the country. They operate on very small holdings using mostly traditional method because, their income is relatively low and the capacity to save is poor. Therefore needs for credit in order to meet the small farmers output and input

In paragraph form (automatic 1-pt deduction if not), explain the evolutionary benefits of sexual reproduction as a means of increasing variation. Be sure to include (a) at least two ways in which sexual reproduction impacts genotype (i.e. genetic effects), and (b) two ways in which sexual reproduction may affect phenotype (i.e. trait effects).
Answer:
See explanation
Explanation:
According to the theory of evolution,species which are better adapted to their environment tend to survive and reproduce in a population passing on these favourable characteristics to their offsprings.
During sexual reproduction, genes can be arranged in new ways from chromosomal crossing over and recombination. This introduces new gene combinations(genotype) and ultimately variation in the population.
This variation may also lead to the observation of new phenotypes in the population.

Explanation:
Phosphates have been banned in most dishwashing detergents in order to
protect the environment. Why were phosphates removed from dishwasher
detergents?
A. Because they buffer cells from extremes in pH
B. Because they increase the acidity of water and cause acid rain
C. Because they increase the salinity of water and pollute drinking
water
D. Because they cause algal blooms that starve fish of oxygen
Answer:
Option D
Explanation:
Seventeen states banned phosphates from dishwasher detergents because the chemical compounds also pollute lakes, bays and streams. They create algae blooms and starve fish of oxygen. ... It just wasn't feasible to make detergent with phosphates for some states and without them for others

The celiac ganglion ________. Group of answer choices is located near the base of the superior mesenteric artery arises from the greater splanchnic nerve projects postganglionic fibers that innervate the small intestine and the kidney and urinary bladder arises from the lesser splanchnic nerve arises from the lumbar splanchnic nerve
Answer:
The correct answer is ''arises from the greater splanchnic nerve''
Explanation:
The greater splanchnic nerve or great adrenal nerve, originates in the thoracic sympathetic chain from vertebral levels T5 to T9 (T10). It runs over the bodies of the thoracic vertebrae and as it descends it becomes more anterior. It enters the abdomen crossing the diaphragmatic pillar and ends at the celiac plexus. The upper part of each celiac ganglion continues with the greater splanchnic nerve. The collateral or prevertebral ganglia innervate the abdominal and pelvic organs and viscera. The celiac ganglion receives preganglionic fibers from T5 to T12 and innervates the stomach, liver, pancreas, gallbladder, small intestine, spleen, and kidneys.
Question 10 of 34
Which of the following best describes the function of the human nervous
system?
A. The nervous system transports oxygen and nutrients to the body's
tissues,
B. The nervous system collects and responds to information about
the internal and external environment,
C. The nervous system protects internal organs and assists with
movement.
D. The nervous system protects the body against infection and helps
regulate body temperature,
Answer:
B. The nervous system collects and responds to information about
the internal and external environment,
Explanation:
The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.
In 1970, Frye and Edidin published research describing the mobility of plasma membrane proteins. They fused mouse and human cells together, creating a hybrid cell, and then examined the localization of mouse and human proteins over time. Initially mouse and human proteins were each restricted to one-half of the heterokaryon, but over time the mouse and human proteins mixed, with each being present over the entire cell surface. What technique did Frye and Edidin likely use to examine the mouse and human proteins
Answer:
The answer is "fluorescent microscopy".
Explanation:
A microscope featuring fluorescence is just the same as a conventional light microscope with additional features. Conventional microscopy employs visible light (400-700 nanometers) to illuminate and generate an enlarged image data. Scientists use this highly sensitive, precise, dependable, extensively to see the location of chemicals in tissues and macrophages in organs.
It is believed that the ratio of cyclic electron transport to Z-scheme photosynthesis changes in response to metabolic demands. If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, how would it alter these processes compared to a plant just performing the Calvin cycle to produce glucose
Answer:
The correct answer is (b) More Z-scheme photosynthesis, less cyclic photophosphorylation
Explanation:
Z-scheme is the schematic flow of the electrons from water to NADP+ and as it connects the two different photosystems that look like z in the diagram it is termed as Z-scheme of photosynthesis. The ratio of cyclic electron transport to Z-scheme photosynthesis alters as per the metabolic requirements. In the question, it is given that If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, then it will acqiuire more z-scheme photosynthesis compared to a plant just performing the Calvin cycle to produce glucose.
Answer: More Z-scheme photosynthesis, less cyclic photophosphorylation
In the Avery, MacLeod, and McCarty experiment, the transforming extract from virulent bacteria was treated with DNase, RNase, or protease before being mixed with nonvirulent bacteria. The appropriate control for this experiment is to treat the transforming extract from heat-killed virulent bacteria with:
Answer:
Nothing
Explanation:
A. Control variables generally entail little or no system change. To see if the method worked, the researchers required a positive control in which the heat-killed virulent bacteria invariably transformed the non-virulent microorganisms. This positive control involves adding "nothing" to both the heat-killed virulent bacteria before mixing them with the non-virulent bacteria.
Hi, guys so I'm doing an experiment and need help finding out the types of variables. In my experiment, I am using a narrow straw, a wide straw, and some colored water to find out how different variables affect capillary action. I'm trying to find out what is the controlled variable, independent variable, and dependent variable.
Answer:
Controlled variable=coloured water
Dependant variable=amount of water
Independant variable=narrow and wide straw
Explanation:
Have a nice day
Answer:
The controlled variable is straws. Independent it the water and dependent is the capillary action.
Explanation:
The Independent variable is the water because its not chaninging thorughout the experiment and has no conqueunces on the other varibales. The controlled is the straws because you are controlling the different diameters in which the straws are (narrow/wide). Then as you change your controlled variable your dependent varible will change- which is the affect on capillary action.

Answer:
Maybe 37°C
Explanation:
Because at 100°C enzyme gets denatured so maybe its 37°C .

eople that have a single allele (gene copy) for sickle cell anemia are typically not sick from the disease and are said to be carriers of sickle cell trait. These people will more often live in the malaria belt of sub-Saharan Africa. The most likely explanation for this is ________. malaria is a cause of sickle cell trait people with sickle cell trait have a better chance of surviving malaria sickle cell trait is passed on to the biting mosquitoes as malaria There is no correlation between a single allele for the pathology and the ability to survive or fight malaria.
Answer: people with sickle cell trait have a better chance of surviving malaria.
Explanation:
Malaria is a very prevalent disease in the malaria belt of Sub-Saharan Africa which includes much of western and central Africa. The people here have therefore grown to have better immunity to malaria by developing the sickle cell trait.
This has helped them survive both malaria and sickle cell anemia which doesn't affect them even though they carry the sickle cell trait.
