In conservation plowing, why are dead weeds and stalks of the previous year's crop left in the ground?
a. to keep the soil from becoming too fertile
b. to reduce the amount of seed needed for the next year's crop
C. to retain moisture and hold the soil in place
d. to keep more organisms out of the soil
Answer:
to retain moisture and hold the soil in place.
Explanation:
this technology of putting dead plants on the soil under the plants and the area nearing the plants is called mulching.it is helpful in reducing the rate of evaporation and also reduces soil erosion.
Conservation plowing is achieved to minimise soil erosion. Thus, option C is correct.
What is soil erosion?Soil erosion is the deterioration of the topmost layer of soil. The top fertile layer of the soil withers leaving the soil infertile.
It is a gradual naturally occurring phenomenon but can be accelerated with human interventions.
There are many factors responsible for soil erosion:
• Deforestation
• Excessive grazing
• Mining
• Construction work
• Drought and floods
Soil erosion negatively affects the crop yield and also clogs the water bodies. This is therefore harmful for the aquatic species. Dry and barren soil is more prone to floods.
Soil erosion should be minimized as it produces a negative impact on the ecosystem.
Soil erosion can be prevented by planting more number of trees. The roots of the trees help in holding the soil in its place.
Therefore, soil erosion should be checked to preserve the soil fertility.

Explanation:
Margaret Mead lived in New Guinea in the 1930s to conduct her study of cultural variation.
What is cultural variation?Cultural variation makes reference to the rich range of cultural practices found in diverse cultures all over the world.
Gender roles, economic systems, and social structure, among a variety of other humanely as possible organized behaviors, all change from one culture to the next.
Margaret Mead conducted actual first-hand observational data of the shared, behavior patterns of several small societies in New Guinea to find out.
Mead chose to live among the people of New Guinea and take part in their activities in order to gain a comprehensive understanding of cultural variation.
Mead was best known as an anthropologist for her research on the nonliterate peoples of Oceania, particularly in terms of psychology and culture.

Whales are marine mammals that share a common ancestor with group of land mammals that includes hippos. Which observation provides evidence of the shared ancestry of whales and hippos? *
Answer:
Genes and amino acid sequences.
Explanation:
The ancestor of whales and hippos are the same because of the same gene and amino acid sequence. The genes and amino acid sequences of living whales were the evidence that shows ancestry of whales and hippos. This evidence indicates that million of years ago both whales and hippos were split from a same ancestor due to evolution.

What new compounds are formed during cellular respiration?
Oxygen & Glucose
Carbon Dioxide & Water & ATP
Water & Oxygen & ATP
Glucose & Carbon Dioxide
Answer:
I think the answer is Carbon Dioxide & Water & ATP.
New compounds are formed during cellular respiration are carbon dioxide,water, and ATP. Thus, option B is correct.
What is cellular respiration?
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP ( Adenosine triphosphate) that can be used by the cell. Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is in cellular respiration, glucose and oxygen react to form ATP ( Adenosine triphosphate)
Adenosine triphosphate is an organic compound which gives energy to living organisms to drive many operations in living cells. such as muscle contraction, muscle pumps, nerve impulse propagation, condensate dissolution, and chemical synthesis.
Respiration is a phenomenon in which metabolic process is take place in the living organisms. It is biochemical process which takes place in the cell of organisms. In respiration energy (ATP- Adenosine triphosphate) is developed by splitting of glucose which will further used by cell to perform various function. Single-celled organisms always dominant over the multicellular organisms.
Therefore, New compounds are formed during cellular respiration are carbon dioxide,water, and ATP. Thus, option B is correct.

What is colon cell?IECs, which line the surface of the intestinal epithelium, are crucial for food digestion, nutrient absorption, the body's defense against infections from microbes, among other functions. Adenocarcinoma, the most prevalent type of colon cancer, develops in the glands that secrete mucus and is the primary cause of colon cancer diagnoses.In order to regulate mucosal immunity, coordinate food recycling, and create a mucus barrier, the colonic epithelium allows host-microorganism interactions. Inflammatory bowel illness is caused by a breach in the epithelial barrier (IBD).A colon polyp is a little cell cluster that develops on the colon's lining. Colon polyps are usually not harmful. But over time, certain colon polyps can transform into colon cancer, which, if detected in its later stages, can be fatal.

The gene for the hair pattern called a "widow's peak" is dominant. In a population of 100 people, 50 people have a widow's peak. How many people would you expect to be heterozygous for the trait?
50 people because the widow's peak is dominant. Those who don't have a widow's peak do not have the gene.
If the gene for the hair pattern "widow's peak" is dominant, it means that individuals with at least one dominant allele will express the trait. We would expect 50 people to be heterozygous (Ww) for the widow's peak trait.
Heterozygous refers to a genetic condition in which an individual possesses two different alleles for a specific gene. Alleles are alternate forms of a gene that can code for different variations of a particular trait. In a heterozygous individual, one allele is dominant and the other is recessive.
The dominant allele is expressed in the phenotype, meaning it determines the physical appearance or characteristic, while the recessive allele remains hidden and does not show in the individual's observable traits. The notation for a heterozygous trait is typically represented by two different letters, one for each allele (e.g., Aa).
Assuming that "W" represents the dominant allele for widow's peak, and "w" represents the recessive allele.
Given that 50 people in the population have a widow's peak (homozygous dominant, WW), we can deduce that the other 50 people must have the genotype for heterozygous (Ww) to express the trait.
