Answer:
circular
Explanation:
Studies of conjugation in multiple Hfr strains revealed that the bacterial chromosome was circular.
Conjugation in bacteria is a process through which genetic materials are directly transferred from one bacterium to another. The process was first discovered by the experimental work of Joshua Lederberg and Edward Tatum in 1946. The donor bacterium first makes a copy of the genetic material by replication and then pass a copy to the recipient bacterium.
It was during the process of conjugation that scientists discovered that the genetic material of the bacteria is a circular chromosome, also known as the F plasmid. The circular chromosome breaks at a particular point and becomes a linear structure before replication and then folds back thereafter. The replicated chromosome is linearly transferred to the recipient cell.

What organelles are associated with carbohydrates?
Answer:
The only organelle that is associated with carbohydrate synthesis is the Golgi Apparatus.
Explanation:
Hope this helps!
The organelles which are associated with carbohydrates are mitochondria and the endoplasmic reticulum (SER).
What are Mitochondria?Mitochondria may be defined as the double-membrane bound cell organelle which is found in the cytoplasm of the cell. It was first recognized by Kolliker in muscle cells of insects in 1880.
Mitochondria are known as the "Powerhouse of the cell". This is because the energy required for various activities is released by mitochondria in the form of ATP. This organelle also oxidizes the pyruvic acid and forms energy in the form of ATP.
The smooth endoplasmic reticulum is directly associated with carbohydrate metabolism along with other metabolic processes like the synthesis of lipids, detoxification, etc.
Therefore, mitochondria and the endoplasmic reticulum (SER) are the organelles that are associated with carbohydrates.

In an organism of genotype Aa, half the reproductive cells carry 'A' and half carry 'a'. Mendel called this
Answer:
The correct answer is - Segregation
Explanation:
An organism with the genotype Aa whose half of the reproductive cell or gametes carry A and the rest of the gametes or reproductive cell carries allele a. According to the laws of Mendel, it is the law of Segregation.
In a diploid organism, the genotype of an individual possesses a pair of alleles (50-50 %) for any particular character and is passed one of each to next-generation from each parent.
Opiate drugs occupy the same receptor sites as: Group of answer choices endorphins. epinephrine. dopamine. serotonin.
Answer:
Endorphins.
Explanation:
This is because endorphins are natural chemicals the body produced in order to relieve the body of pains which also belong to the same categories as opoid because opoid are drugs that are administered to people to relieve them in of pains. They can be prescribed for short term use mainly after a surgery.
Natural Selection is the process by which individuals better suited for survival tend to produce more offspring and over time the population changes to reflect their characteristics.This process can be summarized in 4 steps:
1) ____________ usually results with more offspring being produced that can survive
2) _________exists within any population
3) With limited resources, only individuals with favorable traits are ___________ to survive
4) Over time ,the differential reproductive success results in a population that has _______
Answer:
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

All but one response is a human response to a change in environmental temperatures. That is sweating. The correct option is D.
What is sweating?Sweating is a physiological process that aids in controlling body temperature. Sweating is the expulsion of a salt-based fluid from your sweat glands, which is also known as perspiration.
Four different strategies exist for humans to react to environmental stress: adaptation, developmental adjustment, acclimatization, and cultural reactions.
A genetically based property known as an adaptation has evolved because it aids living things in surviving and procreating in a certain environment.
Sweating can be brought on by changes in your body temperature, the environment, or your emotional state.
Therefore, the correct option is D) sweating.
