What must happen to a chromosome for it to become chromatin?
Answers
Answer:
Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5). ... However, when eukaryotic cells are not dividing — a stage called interphase — the chromatin within their chromosomes is less tightly packed.

2: 1. Body cells make up the body of any multicellular organism. On the other hand, a gamete is a sex cell that can either be a sperm or egg cell.
2. Body cells undergo the process of mitosis while gametes undergo a process called meiosis.
3. A body cell contains a complete number of chromosomes and is called a diploid cell while a gamete contains only half the number of chromosomes of its parent cell, and it is called a haploid cell.
3. Identical twins
4. nucleotide triplets
5. A gene is a sequence of nucleotide bases that specifies certain products; RNA or proteins. It is the segment of DNA that holds the information to build and maintain an organism's cell and also pass genetic traits to offspring. Hence, it is the molecular unit of heredity in living organisms.
The DNA is a long double-helical structure that stores the genetic information in our cells. It consists of two long polynucleotide chains composed of the four nucleotides subunits (A, C, G, T).
In order for the long strand of DNA to fit into the cell's nucleus, it is coiled around certain proteins called HISTONES to form Chromatin, which undergoes further coiling and organization to to linear CHROMOSOMES.
The chromosomes are structured within the nucleus, that are made up of the cell's genetic material (DNA). In eukaryotic cells, the nucleus houses the cell's DNA and directs protein synthesis (expression of the information encoded by genes).

What happens to the genetic material before the cell divides
Answers
Because each chromosome is made from a single molecule of 'DNA', before a cell divides itself, it had to replicate and copy its DNA. This makes it so that after cell division, each new cell holds an exact copy of the genetic material from the original cell.

When is the kinetic energy of a pendulum the least?
Question 5 options:
On the path beginning the upwards swing.
Half the distance on the path traveling back down.
At the bottom of the swing.
At the top of the swing where it briefly stops before changing direction.
Answers
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The Correct choice is ~
" At the top of the swing where it briefly stops before changing direction "
before changing the direction, it stops for a while therefore the kinetics energy is almost zero at that particular moment ~
The answer is D - At the top of the swing where it briefly stops before changing direction. This is where potential energy is at its highest, meaning that kinetic energy is at its lowest. When the pendulum is beginning its upwards swing, it has a lot of kinetic energy. When it is half the distance traveling down it also has lots kinetic energy. When it is at the bottom it as well has a lot of kinetic energy. The only time where the kinetic energy is least is when the pendulum stops to change direction. Any form of stopping forced the object to loose its kinetic energy.

What are some functions of the foot in rotifers? (Choose all that apply)
to propel itself through its environment
to aid in defense against predators
to assist in the digestion of food
to attach itself to a variety of structures
Answers
Answer:
to propel itself through its environment and to attach itself to a variety of structures
Explanation:
I took the quiz(-.-)
Rotifers foot is transformed into a variety of structure for moving and swimming and attach itself to a different structure, hence option d is correct.
What are rotifers?Some rotifers are really planktonic and free-swimming, while others travel around a substrate via inchworming, and some are sessile and reside inside tubes or gelatinous holdfasts.
About 25 species are sessile or planktonic, colonial (such as Sinantherina semibullata), and some rotifer species have evolved four moveable toes that are equipped with pedal glands to facilitate swimming and crawling.
Rotifers swiftly colonize new environments and transform primary production (algae and cyanobacteria) into a form that is secondary consumers.
Therefore foot of the rotifers is changed into a different structure for movement is attach itself to a variety of structures, hence option d is correct.

Walking through a forest you
encounter fallen leaves, dead
organisms, a rotting stump. All of
these can be described as
A. autotrophs.
B. primary consumers.
C. trophic levels.
D. detritus.
Answers
Answer:
D
Explanation:
D is really decomposing waste of anytime so I think that’s the answer.
In a forest fallen leaves, dead organisms, a rotting stump. All of these can be described as detritus, hence option D is correct.
What are detritus in the ecosystem?Detritus is a term used in ecology to describe organic stuff that comes from nearby terrestrial populations and falls onto the soil or into bodies of water, including leaves and other plant parts, animal remains, waste products, and other organic trash.
Detritivorous invertebrates, which are prominent elements of almost all ecosystems, eat detritus, which is a significant pool of carbon in the global carbon cycle.
Therefore, detritus food chains, in contrast to terrestrial food chains, begin with dead organic materials rather than producers or autotrophs, hence option D is correct.

Answers
Fruitflies are advantageous in the study of human genes and inheritance because they reproduce quickly and take up little space.
Advantages of using Fruitflies in the study of human geneticsFruitflies are usually a subject for the study of human genes and inheritance for some reasons:
They have a simple genetic structureThey reproduce quicklyThey are quite small and hence take up very little spaceThe quick rate of reproduction makes fruitflies good subjects for studying mutation as well.

They reproduce quickly and take up little space.
What is inheritance?Fruit flies (Drosophila melanogaster) are advantageous in the study of human inheritance because they have several characteristics that make them well-suited for genetic research. One key advantage is their rapid reproductive cycle, with a generation time of about two weeks. This allows researchers to observe multiple generations in a short period, accelerating the study of inheritance patterns and genetic traits.
Additionally, fruit flies have a relatively small size, making it feasible to maintain large populations in a laboratory setting without requiring excessive space or resources. This allows for efficient experimental design and the ability to conduct large-scale genetic studies.
While fruit flies share some genetic similarities with humans, they are not identical to humans. However, their genetic and developmental processes have enough similarities to provide valuable insights into fundamental principles of inheritance and gene function, which can inform our understanding of human genetics.
