Answer:

A. chromosome

Explanation:

Chromosomes are typically what you see in a chart like karyotype that shows all the chromosomes of a particular organism. These are the highly condensed structures of DNA during replication which makes it easy to transfer DNA during replication.

Answer:

A. Chromosome

Explanation:

Each of your 46 cells has a chromosome, which is a very long strand of DNA with a combined length of around 3 meters! The DNA is wound around protein beads known as histones, and then histones are wound together to form larger and larger organized coils. This is done to prevent them from bunching and knotting together as headphones in your pocket used to before we were all wireless. The volumes of this blueprint, if DNA is the blueprint for everything that goes into creating our bodies, are known as chromosomes. Each of them has an extremely long word that can only be formed using four different types of letters (G, A, T and C). Genetic code is the process by which our body decodes a word to determine its meaning in smaller bits and the location of its genes. Genetic sequence is the term used to describe the letter order. The short arm, centromere, and long arm are the three structural components of each chromosome, which can vary in length. When a cell divides, it makes a copy of the chromosome, and the old and new copies are momentarily clipped to one another by their centromeres. The centromere is a particular segment of DNA that plays a crucial function in this process. Additionally, the centromere contains a "reel" connected to it that pulls the chromosome to each of the separated cells during cell division. Because the size of the chromosome arms is never exactly equal, one must be shorter and the other must be longer. Our genes are located in these arms.

The DNA that makes up the blueprints for all of the proteins your body produces is found in the core of each and every one of your cells.

The DNA organizes itself into 46 distinct bundles when a cell is prepared to divide. which, based just on size and the chains of nucleotides that make up the DNA's "ladder" portion, really seems to be 23 separate pairs of bundles (remember, 99.9 percent of all human DNA is identical from person to person, so the DNA you get from your mother looks an awful lot like DNA from your father). Unless you're a man, in which case you have two misaligned chromosomes and 22 pairs of chromosomes (that would be the "X" and the "Y").

Which organism is a secondary consumer (3rd trophic level)? a. larvae b. copepods c. killifish d. snapper

anygoal [31]

ANSWER: B, killifish

REASONING: A secondary consumer consumes animals that eat only plants. Larvae and copepods do not fit these descriptions, because they do not eat animals. Snapper do eat animals, so do not fit the description either. Killifish eat small animals that do eat plants.

mihalych1998 [28]

<h2>Reproductive Method </h2>

Explanation:

The rank in order from the most specific which is following .

(1) Reproductive isolating mechanism

(2) Sperm-egg incompatibility in sea urchins

(3) Gametic isolation 

(4)Prezygotic isolating mechanism

(1) Reproductive isolating mechanism- The components of regenerative confinement are an assortment of transformative instruments, practices and physiological procedures basic for speciation. They keep individuals from various species from delivering posterity, or guarantee that any posterity are sterile.

(2) Sperm-egg contradiction in ocean urchins- Bindin is a gamete acknowledgment protein known to control species-explicit sperm-egg grip and layer combination in ocean urchins.

(3)Gametic isolation - Prezygotic hindrances keep preparation from occurring. Gametic disengagement is a sort of prezygotic hindrance where the gametes (egg and sperm) come into contact, yet no preparation happens. Gametes might be not able to remember each other in various species

(4) Prezygotic isolating mechanism- while postzygotic segregation forestalls the arrangement of rich posterity. Prezygotic systems incorporate environment segregation, mating seasons, "mechanical" disconnection, gamete detachment and conduct seclusion.

Can someone make me a storyline about protist? It doesn’t have to be a whole story but something I can go off of?

Vitek1552 [10]

Answer:

Protists are a diverse collection of organisms that do not fit into animal, plant, bacteria or fungi groups. While exceptions exist, they are primarily microscopic and made up of a single cell (unicellular), according to the educational website CK-12.

Processes such as changes in orbital geometry or volcanic eruptions have clearly affected climate in the past, and these explain

docker41 [41]

Answer:

TRUE

Explanation:

There has been a constant increase in the earth's global surface temperature. This global rise in temperature is due to the increasing number of volcanic eruptions on earth's surface, changes in the orbital geometry as well as due to the introduction of the industrial revolution, that has been taking place on earth for the last 200 years.

The eruption of volcanoes leads to the release of a large number of pyroclastic materials and greenhouse gases and volcanic gases such as CO₂, SO₂, H₂O, H₂S and many other gases, which is harmful to the atmosphere. This leads to an increasing amount of temperature, resulting in the melting of the glaciers in the polar region.

Over this long time, plate motions have rapidly taken place, due to which the volcanoes were formed and erupted near the convergent and the divergent plate boundaries.

Thus, the above-given statement is true.

Individuals with anorexia nervosa and bulimia nervosa differ in the

Elena-2011 [213]

Anorexia nervosa and bulimia nervosa are both eating disorders, but the main difference is that individuals with anorexia have a tendency to skip meals, while individuals with bulimia go through a cycle of binging (overeating) followed by vomiting. People with anorexia are usually extremely underweight and with an unhealthy figure, while the physical appearance of people with bulimia can be “normal” or sometimes underweighted.
