i can't figure out what a chromosome is. is a chromosome the single thing on the left? or is it the two intertwined sister chromatids on the right?
Answers
So what's a chromatid? Well, during DNA division, when a cell divides, it needs to take its DNA and duplicate it and then transfer half of it to one cell and half to the other cell. Well, DNA's arranged in chromosomes, as you know, so what happens is, as a chromosome replicates, or makes a copy of itself, it's arranged as two chromosomes next to each other, called chromatids. Then during mitosis, when the DNA is transferred to the two daughter cells, one of each of those chromatids is transferred to each of the two cells. So a chromatid is one copy of a chromosome after DNA replication.
Hope this helps
Explanation:
A chromosome is a thread-like structure of DNA (nucleic acids and proteins) that carries genes. The "X" and "Y" gene that determines whether you will be a boy or a girl.

B. Asexual reproduction has 1 parent with identical offspring
C. Asexual reproduction has 2 parents with similar offspring
D. Asexual reproduction has 2 parents with identical offspring
Answers
Answer:
A.)
Explanation:
We know that asexual means one. In this case, it would be A
., because there is one parent producing the cells. There may be some differences, which would make similar offspring, not identical offspring. So the answer would be A.) :) Hope this will help!
In the animal kingdom, wild wolves joined hunter-gatherers in East Asia, where canines were domesticated and bred to have increased docility. Over thousands of years, people bred dogs with different desired personality and physical traits, eventually leading to the wide variety of dogs we see today.
Phosphorus is necessary for the growth of healthy plants. Scientists are developing plants that can grow in phosphorus-poor soil. Some of these new varieties, produced in a lab, make extra copies of a protein that helps plants obtain more phosphorus from the soil.
Breeding dogs for certain traits is a way of modifying outcomes but today's advances have enabled us to actually change certain outcomes through technology
The process being used to develop these new varieties is most likely: (SC.912.L.16.10)
A. natural selection
B. Conversely, paper chromatography
C. direct harvesting
D. genetic engineering
Answers
Doesn’t matter if it takes hundreds of years or a couple weeks, if there is an intent to alter the genes of an organism to select for desired traits, it is genetic engineering.
The process is used to develop these new varieties is most likely genetic engineering (Option D).
What is genetic engineering?Genetic engineering refers to the techniques used to modify the genetic material of an organism.
Genetic engineering techniques include, among others, recombinant DNA and genome editing systems.Genetic engineering is very useful to obtain organisms that synthesize desired proteins or crops that have desired phenotypic features.In conclusion, the process is used to develop these new varieties is most likely genetic engineering (Option D).

In aerobic cellular respiration the products are ATP, CO2, H20, where as the reactants are 02 and glucose
What is the difference between aerobic and an-aerobic cellular respiration ?Cellular respiration is just opposite to photosynthesis where glucose break down to produce energy in the form of adenosine triphosphate or ATP.
If It occurs either in presence of oxygen called aerobic respiration and in absence of oxygen called anaerobic respiration.
Aerobic respiration where organism combine oxygen with food substances and produce biochemical energy in the form of ATP, release carbon dioxide, and water as by product.
It occurs in inner membrane of the mitochondria.
Example is glycolysis.
Anaerobic respiration occurs in the absence of oxygen, involve break down of sugar into lactate and it occurs in Cytosol of cell.
Fermentation is example of anaerobic respiration.
