Answer:
Bones are composed of two types of tissue:
1. Compact (cortical) bone: A hard outer layer that is dense, strong, and durable. It makes up around 80 percent of adult bone mass.
2. Cancellous (trabecular or spongy) bone: This consists of a network of trabeculae or rod-like structures. It is lighter, less dense, and more flexible than compact bone.
Also found in bones:
osteoblasts and osteocytes, responsible for creating bone
osteoclasts or bone resorbing cells
osteoid, a mix of collagen and other proteins
inorganic mineral salts within the matrix
nerves and blood vessels
bone marrow
cartilage
membranes, including the endosteum and periosteum

What does RNA do?
Is it just me or is every telling me to just die today.... like many of my friends said i should just kiII myself, that it would be better for everyone because no one would miss me... or is that juts me?
Answer:
The RNA carries out these instructions; it copies and transfers the genetic code from the DNA to ensure the relevant proteins are made. So just think of it as “DNA makes RNA make proteins”. Whereas DNA stands for deoxyribonucleic acid, RNA stands for ribonucleic acid.

O
D. The organs in an organ system work together to perform all the functions a multicellular organism needs to maintain homeostasis.
Answer:
C. The organs in an organ system work together to perform a specific function.
Explanation:
The definition of an organ system is a "group of organs that work together as a biological system to perform one or more functions". Each organ in a system does a different job in order to achieve the same goal. For example, the stomach breaks down food, and the intestines gather nutrients but the goal of both is to digest food.

Would the distance from the Sun to the next closest star be more or less than
39.4 Astronomical Units? Why or why not?
Answer: The distance from the sun to the closest star would be less. I dont know why, but their is a star that is close to the sun. The average distance between them is about 23 astronomical units. 23 is of course less then the 39.4. Also the 23 is a little more than the distance between the sun and Uranus.
Explanation: ( This is new information, not old.)
The distance from the Sun to the closest star cannot be less than 39.4 AU because both stars will start attracting each other.
Astronomical Units:An astronomical unit is equal to the distance between the earth and the sun.The nearest star from our sun is Alpha Centauri which is 4.367 light-years away from our sun.If a star is just 34 astronomical units away from our sun, the sun and the closest star will start attracting each other due to the high gravitational force. This event results in the destruction of the solar system.Therefore, the distance from the Sun to the closest star cannot be less than 39.4 AU.

The diagram that explains the crossing over in the following diagram is option C, as here the crossing over takes place and the chromosomes exchange their genetic materials and can later produce the gametes.
What exactly is the significance of the cross-over in meiosis?Crossing over is important in meiosis because it occurs when homologous chromosomes exchange genetic material, resulting in the formation of new combinations of genetic information and increasing genetic diversity in the population. As a result, evolution occurs, and unique offspring are produced.
Hence, the diagram that explains the crossing over in the following diagram is option C, as here the crossing over takes place and the chromosomes exchange their genetic materials and can later produce the gametes.

He continued to breed purple-flower producing pea plants together over six generations. The results of Ralph's artificial selection are shown above. What did artificial selection do to the population of pea plants? A. caused a new species of pea plant to form B. increased its genetic diversity C. decreased its genetic diversity D. caused a pea plant to exhibit a new characteristic
Answer:
C
Explanation:
The correct answer would be that artificial selection decreased the genetic diversity of the pea plant.
Genetic diversity is a measure of the number of traits or characters.
Initially, the breeding produced a considerable population of both white and purple flower offspring. But as time goes on, the population of purple flower offspring increased while that of the white flower decreased till it eventually reached zero.
Thus, artificial breeding reduced the number of traits in the population of the offspring from two to one - a case of reduction in genetic diversity.
The correct option is C.

Why scientific naming is necessary?
Answer:
The correct answer would be - to communicate unambiguously globally.
Explanation:
In different locations on the earth or countries, there are thousands of languages present, and each language has a name for the different species or different organisms that leads to confusion and tough to take the record.
Therefore, there is a two-part scientific name system proposed for every species first name for the genus and second part for the species, it is called "binomial nomenclature." It helps and allows to communicate unambiguously about the species of different organisms globally.

whats this,in order?
Answer:
1. Individuals in a species vary in characteristics because of differences in their genes.
Individuals will be born with various characteristics due to their genes for instance some people are short and other are tall.
2. Individuals have to compete when resources (such as food) are limited.
Resources are generally limited so individuals would have to compete t get those resources and survive.
3. Individuals with variations that help them get more of the resources are more likely to survive.
Some of the characteristics that these individuals have which are different will give them an edge and enable them to get more resources and thus survive.
4. Individuals that survive can pass their genetic variations on to their offspring.
The individuals that survive will now have offspring and will pass on their genes to their offspring which give give them the same edge their parents had.
5. Over time, there are more individuals with the variations that are well adapted to the environment.
Eventually there will be more of those offspring that can adapt as opposed to those who couldn't and keep dying out.

Which of the following characteristics of a population will make it better able to adapt to environmental changes?
A.Rapid production of many offspring.
B.Specialization in one type of food source.
C.Large amount of inherited genetic variation.
D.Isolation to a limited geographic range.
Answer:
C
Explanation:
Answer: C. Large amount of inherited genetic variation.
If you had a population where the genetic variation wasn't as high or practically non-existent, then that population is likely suited to that very narrow specific environment. If the environment doesn't change, then the population wouldn't have a problem. However, the environment isn't likely to stay static. Things change all the time and this change will bring challenges to the population that was suited for the old environmental conditions.
Populations with high genetic variability will have some individuals thrive while some unfortunate members will perish. The members that die off are likely the ones who cannot adapt to the changes. As the environment changes, the individuals who survive will pass on their DNA to their offspring, allowing for natural selection to reinforce those favorable traits. Since the environment is constantly changing, whether that change is slow or fast, this means the process is continued indefinitely. So that's why high genetic variability is favored.

1. What is the overall purpose of mitosis and meiosis?
2. Why is it important that DNA is replicated prior to cell division?
3. How are normal cells and cancer cells different from each other?
4. Describe mistakes that can occur during the cell cycle and cause human disorders.
Mitosis aims to create daughter cells that are completely genetically similar to their mothers, with no extra or less chromosomes. In contrast, meiosis serves a single function in the human body that is the creation of gametes.
What is cell division?The process by which a parent cell divides into two daughter cells is known as cell division. Cell growth and chromosome replication precede cell division, which often happens as part of a longer cell cycle.
Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.
Grow in the absence of signals instructing them to do so in cancer cells. Only when they get such signals do normal cells expand. Disregard cues that would typically instruct cells to cease dividing or die.
Aneuploidy is a condition when there are either too many or too few chromosomes in the daughter cells produced during mitosis.
Thus, this is the overall purpose of mitosis and meiosis.

1. The overarching goal of mitosis is to ensure cell division and the transfer of genetic material to daughter cells for tissue repair, growth and development.
2. To maintain genetic integrity, DNA replication is necessary prior to cell division.
3. Cancer cells have uncontrolled growth, escape cell death and lack contact inhibition, whereas normal cells have controlled cell division, experience programmed cell death and show contact inhibition.
4. The disorders in humans can result from errors in the cell cycle. Diseases such as Down syndrome are caused by abnormal chromosomes. Gene changes can affect the development of cancer.
Meiosis produces gametes for sexual reproduction, while mitosis assures cell division for growth, development, and tissue repair. Accurate transmission of genetic information and preservation of genetic integrity in daughter cells depend on DNA replication prior to cell division.
Whereas cancer cells have uncontrolled proliferation, escape from cell death, and lack contact inhibition, normal cells have regulated division, programmed cell death, and appear to have contact inhibition. Human disorders such as chromosomal abnormalities (such as Down syndrome), gene mutations that cause cancer, errors in DNA replication or repair that cause genetic disorders, and cell cycle control that leads to uncontrolled cell division and tumor formation, all of which Mistakes made during this can have consequences. cell cycle.
