Leukemia is a malignant progressive disease in which the bone marrow and other blood-
forming organs produce increased numbers of immature or abnormal white blood cells.
Which statement about cell cycle checkpoints describes how this disease occurs?
A Dysfunctional checkpoints may lead to abnormal cell growth.
B Defective checkpoints result in death of a cell.
C Normal checkpoints assess damage to cancer cells.
D Cell checkpoints fail only in meiosis.
What would this be.

Answers

Answer 1

Answer:

A Dysfunctional checkpoints may lead to abnormal cell growth.

Explanation:

One of the hallmarks of cancer is unregulated cell proliferation. This means cells keep dividing, producing large numbers of often abnormal cells.

There are many of ways this can happen, such as increased signals telling the cells to divide, and dysfunctional cell cycle checkpoints that do not stop the cell from dividing. This leads to the accumulation of mutations and abnormal cell growth.

Answers

Answer:

B. Two cells, but half the size

Explanation:

Single-celled organisms, which are also referred to as unicellular organisms, usually have a growth mechanism or process known as binary fission.

Binary fission is a an asexual reproduction process that involves the division of a mature parent cell into two identical daughter cells of equal sizes that are almost half of their parents cell.

What differentiates passive transport from active transport?

Group of answer choices

Molecules move down a concentration gradient during passive transport.

Passive transport involves molecules moving across the cell membrane.

ATP is needed for passive transport to occur.

Proteins have a role in passive transport.

Answers

Answer:

The movement of molecules across a membrane without the input of energy is known as passive transport. When energy (ATP) is needed, the movement is known as active transport. Active transport moves molecules against their concentration gradient, from an area of low concentration to an area of high concentration

Column shaped clouds usually mean that heavy precipitation is on the way.  

A fair amount of the world's precipitation falls as snow or some other solid water form. Actually, outside the tropical regions, it is likely that the much of the precipitation begins in the solid form and only becomes liquid rain when it melts while falling through air with temperatures above freezing.

Do you have more cells now than you did when you were five?

Answers

Answer:

No After your cell dies of another one come. Your cells are still the same

Explanation:

When you age, cells do divide and reproduce more cells. However when you age the reproduction process of cells gets slower and they can die off before they can reproduce. There can be many problems with your cells that can make cell count lower such as Atrophy, and Dysplasia. When you age, cells are a contributing factor of making you age. They can change your skin, face, etc.. So the answer would be no, you would not have more than you did when you were five.

Compared to the Sun, the star Betelgeuse is
A. Less luminous and warmer
B. Less luminous and cooler
C. More luminous and warmer
D. More luminous and cooler

Answers

The answer to that is A

Red supergiant star Betelgeuse is around 764 times as massive as the Sun. To put that into perspective, the diameter of Mars' orbit around the Sun is 328 times that of the Sun. Thus, option A is correct.

What is the comparison of Sun and star Betelgeuse?

Betelgeuse is 640 light years away from the sun. Given that the star is only 10 million years old, it will die young like earlier supergiants.

The sun, in contrast, is only approximately halfway through its life and is nearly 4.6 billion years old.

Betelgeuse is one of the gleaming stars in the night sky and can be seen clearly on the right shoulder of the constellation Orion.

Betelgeuse is a red supergiant that is 1,400 times bigger than our Sun and thousands of times brighter.

Therefore, Compared to the Sun, the star Betelgeuse is  Less luminous and warmer.

Explanation:

Arrows have come to represent protection and defence from any evil that can come to you. Sustenance – Arrows were used to fight enemies and to hunt food, two important aspects of sustaining life. As a result, an arrow symbolizes maintaining and protecting life.

REAL NAME - SHRESTH DUBEY

The arrows in a food chain represent the flow of energy or the transfer of nutrients between different organisms in an ecosystem.

They indicate the direction of energy transfer, showing which organism is being consumed by another. The arrow always points from the organism being consumed (prey) to the organism consuming it (predator).

The primary producers, such as plants or algae, are at the beginning of the food chain and transfer energy to herbivores (primary consumers), which are then consumed by carnivores (secondary consumers) or other higher-level consumers.

The arrows help depict the interconnectedness and energy flow within an ecosystem, illustrating the feeding relationships between organisms.

During cell reproduction, chromatin fibers coil up into structures called

a. chromosomes
b. lysosomes
c. nucleoli
d. ribosomes

Answers

it is a. chromosomes

During cell reproduction, chromatin fibers coil up into structures called chromosomes. Therefore, the correct option is A.

What are chromosomes?

Chromosomes are structures made up of DNA and proteins that are found in the nucleus of the cell. They contain genetic information That are responsible for the inherited characteristics of the organisms such as eye color, hair color, height etc.

Chromosomes play a crucial role in cell division, as they ensure the proper distribution of genetic material to the daughter cells.

During cell division, chromosomes are replicated and then separated into daughter cells, ensuring that each cell receives a complete set of chromosome.

The number and arrangement of a chromosome vary depending on the species, but all human cells except the sperm and egg cell contains 23 pairs of chromosomes. Hence, the correct option is A.
