Answer:
Where the cell divides
Explanation:
I think the equator, or equatorial plate, is the midline of the cell where duplicated chromosomes position during mitosis.
The equator of a cell is where equator divides.
Cell:
Cell is the basic unit of life. There are two types of cell : prokaryotic cell and eukaryotic cell. Cell divides by the process of mitosis and meiosis. Mitosis is an equational division and meiosis is reductional division.
Cell division is important for cell growth and division. Cell division starts at the nucleus. In nucleus there are different chromatin material. Chromatin condensed and form a chromosome.
Cell division starts at the equator of the cell. There are four phases : Prophase, metaphase, anaphase and telophase. During metaphase all the chromosome align at the equator.
Therefore, The equator of a cell is where equator divides.

Which of the following is a correct statement about evolution?
A. Evolution is a change in the morphological characteristics of a species
B. Evolution is a change in size characteristics of a species
C. Evolution is a change of allele frequency from one generation to the next
D. Evolution is the change in the physiological characteristics of a species
E. All answers are correct
Answer:
C. Evolution is a change of allele frequency from one generation to the next
Explanation:
Evolution is the gradual change that occurs to living organisms over successive generations. According to Charles Darwin, these changes aid in the adaptation of the species of an organism to their environment. In other words, it makes them better fit.
Charles Darwin further stated that since evolution is dependent on natural selection i.e selection of the best fit by environmental factors, the changes that the organism undergo are genetic. Hence, evolution is a change of allele frequency from one generation to the next.

I’m stumped anyone know 4 metamorphosis facts?
Answer:
Insects that have complete metamorphosis have four life stagesInsects going through their immature stage are called larvaeInsects then enter an inactive state called pupa, or chrysalis. Whilst inside the pupa, the insect will excrete digestive juices, to destroy much of the larva’s body, leaving a few cells intact.In the final stage of the metamorphosis, the insect finally breaks through the pupa emerging as a full adultExplanation:
compare blood cells to plant cells, include details about color, general shape, and size.
Blood cells are red, squishy, rounded, and have an indentation in them in the middle. Plant cells are green and firm and have a more square, boxy shape. Plant cells are larger than blood cells.
Plant cell is different in size, colour and shape from blood cell.
Plant cell has cuboid shape whereas blood cell has biconcave discoid shape. The colour of blood cell is red if it has oxygen or brown if it is no oxygen whereas plant cell has green colour. Plant cells have cell walls, ribosomes, endoplasmic reticulum, DNA and lysosomes but blood cells have no ribosomes, no endoplasmic reticulum, no DNA molecule and no lysosomes. The size of blood cell is 6.2–8.2 µm whereas the size of plant cell has 10 to 100 micrometers so we can conclude that there are a lot of differences between plant and blood cells.https://brainly.com/question/21283369
Despite the fact that the various protists observed in this exercise belong to different
eukaryotic lineages, what makes them all "plantlike" in nature?
Complete question: This can be seen in the attached file below. It's contains the various protists observed in the exercise.
Answer: For a eukaryotic organism to possess a plantlike characteristics shows its ability to manufacture its own food through the process of photosynthesis.
Explanation:
Protists are single- celled or unicellular organisms. They are made up of eucaryotic cells in which the cell structure is complex with a well - defined nucleus. Typical example if protists includes the following:
--> Volvox
--> Spirogyra
--> Euglena
--> Diatoms
--> chlamydomonas
Some protists are said to be plant like and are known as protophyta. Example of such includes Euglena, Spirogyra and chlamydomonas. This is because they have organelles called chloroplasts. This contains chlorophyll which enables them to make their own food through the process of photosynthesis. Photosynthesis is the process by which energy for sunlight is converted to high energy containing organic compounds such as glucose.

achondroplasia is a form of dwarfism in humans. it is caused by a mutant allele of the fibroblast growth factor receptor (fgfr) gene that produces an overactive protein. having one copy of the mutant allele results in dwarfism. having two copies of the mutant allele results in stillbirth. (infant dies in the womb.) which allele, the mutant allele or the wild-type allele, is dominant with respect to viability
Answer:
The correct answer is - wild type in respect of viability.
Explanation:
Achondroplasia is a condition of dwarfism and it takes place due to a mutant allele which autosomal dominant in nature which means only one copy of the mutant allele is going to cause dwarfism in an individual.
We also know that if two copies of the mutant allele are present then it will be lethal and will not be viable so in respect of expression the mutant allele is dominant, however, in respect of the viability, the wild type is dominant.
what factors determine how much the motion of the air molecules will change
The factors that determine how much the motion of the air molecules will change are:
.The rate of diffusion which is affected by the concentration gradient, .membrane permeability.temperature.pressureThe movement of substances from a region of higher concentration to a region of lower concentration is called diffusion of particles. This phenomenon is very important in cellular transport in plants.
The rate of diffusion is affected by 4 factors namely:.concentration gradient: Diffusion takes place when there is a difference between the concentrations of a substance across a barrier. Diffusion stops when the concentrations of the substance on either side of the barrier become equal.
.membrane permeability: Diffusion rate increases as membrane permeability increases.
.temperature and pressure is paramount in the diffusion of gases as gases diffuse from a region of higher partial pressure to a region of lower partial pressure. Same as in terms of temperature.

The two major cell organelles involved in energy transformation are mitochondria and chloroplasts. Thus option A is correct.
what is function of chloroplast ?Chloroplasts are the cellular organelle found in photosynthetic organism like plants and algae.
They are present in mesophyll cells of leaves and contain a high concentration of chlorophyll which absorb sunlight; It is absent in animal cell.
Chloroplast has extra-nuclear DNA and are semiautonomous.
They synthesize food by the process of photosynthesis by absorbing sunlight into chemical energy.
It is major production house of NADPH and molecular oxygen (O2) by photolysis of water; It produces ATP from photosynthesis.
