What happens during meiosis I? *
a. Chromosomes line up in pairs, separate, forming haploid cells
b. Chromosomes line up in pairs, separate, forming diploid cells
c. Chromosomes line up single file, separate, forming haploid cells
d. Chromosomes line up single file, separate, forming diploid cells
Answer:
What is c. Chromosomes line up single file, separate, forming haploid cells
In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity. DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis.

Answer:
C
Explanation:
because one parent divide to give two daughter cell
3. What is the relationship between the lungs of a human and the chloroplasts of a greenhouse plant
in the oxygen cycle? (4 points)
Answer:
they both take in air. chloroplasts take in CO2, and filter it into air. the Lungs breathe that air, and make CO2, which starts a cycle. Hope this helped!

Explanation:
What types of substances will need the help of various proteins for transport?
Explanation:
Ions, sugars, amino acids, and sometimes water cannot diffuse across the phospholipid bilayer at sufficient rates to meet the cell's needs and must be transported by a group of integral membrane proteins including channels, transporters, and ATP-powered on pumps
Does an enzyme change the reactants/products permanently? Explain.
Answer:
No, because the change of the equilibrium constant for a reaction. Keq depends only on the difference in energy level between reactants and products.
Explanation:
Which structural data is normally used to classify mosses into the category Bryophyta?(1 point)
They are large.
They lack roots.
They produce flowers.
They produce seeds.
Answer:
They lack roots
Explanation:
The structural data which is normally used to classify mosses into the category Bryophyta is that they lack roots. Thus, the correct option for this question is B.
What are the characteristics of Bryophyta?The characteristics of the Bryophyta are as follows:
The plant body is mostly thallus-like, i.e. erect or prostate.They are generally attached or linked to the substratum by rhizoids. They significantly lack true vegetative structure. The plants are generally green and have chloroplast.They express an autotrophic mode of nutrition.Vascular tissues like the xylem and phloem are completely absent.It is known that Bryophytes include embryophytes like hornworts, liverworts, and mosses. These are very small plants that remarkably grow in shady or damp areas where there is an enormous amount of mud is present.
Bryophytes have no roots, leaves, or stems. This characteristic is the root foundation or evidence that is used to classify mosses into the category of Bryophyta.
Therefore, the correct option for this question is B.

A population of fruit flies
Answer:
Yes your correct, there are populations of fruit flies.
how the function of the basal cells depends on the relationship among its parts?(respiratory system )
Answer:
Basal cells are found at the bottom of the epidermis — the outermost layer of skin. Basal cells produce new skin cells. As new skin cells are produced, they push older cells toward the skin's surface, where the old cells die and are sloughed off.
Answer:
The respiratory system works directly with the circulatory system to provide oxygen to the body. The primary function of the respiratory system is to deliver oxygen to the cells of the body's tissues and remove carbon dioxide, a cell waste product.Respiratory systems work together to circulate blood and oxygen throughout the body.The respiratory system subdivides into a conducting portion and a respiratory portion. The majority of the respiratory tree, from the nasal cavity to the bronchi, is lined by pseudostratified columnar ciliated epithelium. The bronchioles are lined by simple columnar to the cuboidal epithelium, and the alveoli possess a lining of thin squamous epithelium that allows for gas exchange.The conducting piece of the respiratory system consists of the nasal cavity, trachea, bronchi, and bronchioles. The luminal surfaces of this entire portion have a lining of ciliated pseudostratified columnar epithelium and contain goblet cells. Their role is to secrete mucus that serves as the first line of defense against incoming environmental pathogens. Cilia move the mucus-bound particulate up and away for expulsion from the body. The various types and abundance of cells are dependent on which region of the airway they are.

What is the difference between a vertebrate and invertebrate?
a vertebrate is an organism with a spinal cord, an invertebrate has no spinal cord
Answer:Vertebrates are animals that have a backbone inside their body. The major groups include fish, amphibians, reptiles, birds and mammals. Invertebrates don't have a backbone. They either have a soft body, like worms and jellyfish, or a hard outer casing covering their body, like spiders and crabs.
Explanation:
how plating trees can be a problem
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
There are even more serious issues, as trees have several ways of influencing the climate. The first problem is that trees are dark in comparison to other things that could cover the ground, such as grass or snow. Planting more trees, as a result, tends to make the terrain darker.
Tree planting on a large scale is becoming a more popular part of worldwide efforts to fulfil climate objectives. Forests, on the other hand, are complex ecosystems, and haphazard planting can actually raise carbon dioxide (CO2) levels in the atmosphere, contributing to global warming.
Fact: Trees grow slowly
Protein Folding Notes
Answer:
"Protein folding occurs in a cellular compartment called the endoplasmic reticulum. This is a vital cellular process because proteins must be correctly folded into specific, three-dimensional shapes in order to function correctly. Unfolded or misfolded proteins contribute to the pathology of many diseases."
Explanation:

a. Analysis of data
b.Collection of experimental data
c.Formulation of a hypothesis
d.Formulation of a theory
Answer:
d. formulation of a theory
Answer:
D. Formulation of a theory.
Explanation:
A scientific theory is a set of statements that, when taken together, attempt to explain a broad class of related phenomena.
An -ate or -ite at the end of a compound name usually indicates that the compound contains ____.
Select one:
a.
fewer electrons than protons
b.

d.
a polyatomic anion
Answer:
d. a polyatomic anion
Explanation:
ate and -ite are commonly used for polyatomic ions of Oxygen. - ate is used for the ion that has the largest number of Oxygen atoms. the -ite would be used for the ion with the smaller. NO2 and NO3 are known as Nitrite and Nitrate respectively.
