In the 18th century, Carl Linnaeus published a system for classifying living things, which has been developed into the modern
classification system. Recently the classification system of life was changed to include not five but six kingdoms, as well as
three domains. Earlier classification attempts were based mostly on structural features. Classification of many species, old and
new, continues to be hotly disputed as scientists find new information or interpret facts in new ways. Now, DNA technology
has allowed scientists to re-examine the relationships between organisms to refine the classification system.
One of the modern kingdoms contains organisms with a wide variety of characteristics, including: unicellular or multicellular,
autotrophs, ingestive heterotrophs, or absorptive heterotrophs, They can live in water, soil, and even living bodies. They are all
eukaryotes. Which kingdom is best described here?
)
A)
Fungi
B)
Protista
Bacteria
D)
Archaebacteria
Answer:
A
Explanation:
Products enter a reaction and reactants come out of a reaction true or false?
Answer:
[tex]\boxed {\boxed {\sf False }}[/tex]
Explanation:
In a chemical reaction, the products are produced. The reactants are the substances that react.
In a chemical reaction equation (with the arrow pointing right) the reactants are on the left and the products on the right.
[tex]reactants \rightarrow products[/tex]The reactants enter and the products come out.
So, the statement given - products enter a reaction and reactants come out - is false and it is actually the other way around.

Which three processes occur during meiosis?
a. Crossing over
b. Asexual reproduction
c. Formation of gametes
d. Independent assortment
e. Production of diploid cells
Answer:
a,c,d
Explanation:
A. crossing over
c. formation or segregation
d. assortment
The three processes that occur during meiosis may include crossing over, formation of gametes, and independent assortment. Thus, the correct options for this question are A, C, and D.
What is Meiosis?Meiosis may be defined as a type of cell division in which each parental cell produces four daughter cells. These daughter cells are genetically unique to their parental cells and are haploid in nature. Gamete cells are divided through this method of cell division.
Crossing over is the process that occurs during the Pachytene stage of Prophase 1 of meiosis 1. It involves the exchange of genetic material between homologous chromosomes. The production of diploid cells is the characteristic feature of mitosis, not meiosis. While asexual reproduction of formed by mitosis.
Therefore, the correct options for this question are A, C, and D.

What are 3 characteristics of producers
Answer:
The best examples of producers are plants, lichens and algae, which convert water, sunlight and carbon dioxide into carbohydrates.
Answer:
Producers make their own food. They do not have to obtain energy from other organisms. They obtain their energy from the sun and make food with that energy through the process of photosynthesis. Producers may also be called autotrophs.
Explanation:
Two sharks were raised in the same environment by different parents. They have different proteins in their cells for the color on the tip of their fins. What can you say about the color on the tip of their fins?
A. The fins will be the same color since all sharks have the same fin color even if they were raised in different environments.
B. The fins will be different colors since offspring from different parents will have different colored fins.
C.The fins will be different colors since offspring from different parents will have different colored fins.
D. The fins will be different colors since their proteins will connect in different ways to determine fin color.
Answer:
The fins will be a different color since their proteins for fin color are different so the proteins will connect in different ways.

Explanation:
Certain cells, such as those along the digestive tract, need to absorb a lot of materials. What unique functions do you notice about the shape of these cells? How might this improve their ability to absorb materials?
Answer:
Microvilli is very common in these cells. They increase the absorption area.
Explanation:
Epithelial cell surfaces show different structure shapes that allow the cells to adapt to and accomplish their functions. Most of these structures are related to the absorption surface and the need to move substances.
The development of microvilli is very common in epithelial cells. These are folds or finger-like projections emerging from the apical surface of the cell. Their principal function is to absorb. The microvilli of the intestinal epithelium are very uniform in size and distribution.

After reading the prompt, your teacher has asked you to predict the
effects of the disappearance of snow and ice on this rabbit population
for the future. Which graph BEST represents the correct prediction?
Answer:
I am not 100% sure but try B
Explanation:
The effect of the disappearance of ice and snow on the rabbit population in Northern Canada white rabbit population is higher, hence option b is correct.
How rabbit population changes?Due to the fact that both white and brown rabbits have an equal chance of surviving throughout the year, the population of rabbits is in genetic equilibrium.
While white rabbits stand out and are more likely to be eaten during the summer, brown rabbits are more conspicuous throughout the winter and are more likely to be eaten by predators.
Therefore, in the graph rabbit population for the future is predicted due to snow and ice disappearance and in Northern Canada, white rabbit population is higher in number, hence option b is correct.

A cell with 20 chromosomes undergoes MEIOSIS. Which of these statements is true?
1 Point)
a. 4 daughter cells will be created and each daughter cell will have 10 chromosomes.
b. 2 daughter cells will be created and each daughter cell will have 10 chromosomes.
c. 4 daughter cells will be created and each daughter cell will have 20 chromosomes.
d. 2 daughter cells will be created and each daughter cell will have 20 chromosomes.
Answer:
A.
Explanation:
By the end of meiosis 4 daughter cells will be produced with half the amount of chromosomes the original parent cell has, haploid.
A cell with 20 chromosomes undergoes meiosis produces 4 daughter cells and each daughter cell will have 10 chromosomes. Thus option A is correct.
What is Meiosis?The cell division in which a cell divides twice to form four haploid daughter cells called as Meiosis.
The cell division occur in two steps nuclear division or karyokinesis and cytoplasmic division called as cytokinesis.
This type of cell division are seen in sexually-reproducing organisms mostly germ cells.
During reproduction diploid organism produces haploid number of gametes such as egg and sperm.
The gametes unite to create a new zygote with the same number of alleles as the parents.
The meiosis occur in 2 stages that is meiosis I, meiosis II and Each stage is classified into several phases such as Prophase, Metaphase, Anaphase, Telophase, Cytokinesis.
Prophase I of meiosis I can have five subphrases, such as Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis.
Hence, option A is correct.
