18. How has the use of herbicides affected agricultural productivity?
O A. Fewer crops are organic because of the use of Bt toxin.
B. Fewer pesticides are needed because of parasitoids.
O C. Fewer people are needed to weed because of herbicides.
D. Fewer crops are produced because of herbicides.

Answers

Answer 1

Answer:

B. Fewer pesticides are needed because of parasitoids.

Explanation:

Herbicides are chemicals utilized to manage or command unwanted vegetation. Herbicide employment happens most commonly in row-crop cultivation, where they are employed before or throughout seeding to maximize yield productivity by decreasing other vegetation.  Yields have improved considerably, and, in association with tillage, herbicide use decreases erosion, fuel usage, greenhouse gas discharges, and nutrient run-off, and preserves water.

true or false:

Fish are considered carbon-based organism

Answers

Answer:

Its how you see it.

Explanation:

1.Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.

2.All life on earth can be thought of as "carbon-based." Just be careful about turning this around backwards. It is true that all living things contain carbon compounds... but the opposite is not true. Just because a certain material is referred to as organic does not mean it is or ever was alive.

Answers

I believe the answer is A!!!!!

Agricultural technology has evolved over time, with significant leaps during the agricultural and green revolutions.

Agricultural revolution

Agriculture has been one of the sustainers (along with hunting) of early men and as such, has seen gradual development with time. Man has always been looking for better ways to do things in order to achieve outcomes.

With the era of the agricultural revolution, there was a huge transition of humans from the primitive lifestyle of hunting and fruit gatherings to that of agricultural settlements. Better ways to carry out crop production started receiving huge attention. from there, hand-made agricultural equipment started surfacing.

The green revolution has agriculture receiving utmost attention in terms of technological innovations. Farm machinery, agrochemicals, etc, started coming up with the result being a massive increase in crop production and general outputs.

What are things we can learn from examining hair? Three parts of hair?

Answers

Answer: The hair is an outgrowth or appendage that grows from a hair follicle.

Explanation:

The three parts of the hair are cuticle, cortex, and medulla. The cuticle is the hard part made up of scales with keratin protein, cortex is the inner pigmented part, and the medulla is the innermost part of the hair.

During hair examination the type of cuticular scales helps in determining the organism to which it belongs, diameter of the medulla also helps in determining the organism, the DNA analysis of the hair can link to its origin, the detection of heavy metal poisoning like lead, arsenic, and others. Drug abuse details can also be determined by the hair analysis.

A conjugated protein is a protein that functions in interaction with other (non-polypeptide) chemical groups attached by covalent bonding or weak interactions. ... The non-amino part of a conjugated protein is usually called its prosthetic group. Most prosthetic groups are formed from vitamins. Hemoglobin is a protein having a globular structure. Based on its structural properties, hemoglobin can be divided into two parts; a protein part and a heme group. The structure of the protein part can be studied at four levels; primary structure, secondary structure, tertiary structure, and quaternary structure.

What is the importance of Mitosis in both Prokaryotic and Eukaryotic Cells

Answers

Answer:

Mitosis is the process by which the overwhelming number of cell divisions in eukaryotic organisms occur. Eukaryotes (animals, plants and fungi) typically consist of literally trillions of cells, and at any time, countless worn-out, dead or irreparably damaged body cells need to be replaces. Mitosis is the eukaryotic answer to binary fission in the single-celled prokaryotes, which is similar on the surface but simpler at the level of details.
