Duplicate chromosomes line up (in a single line) during metaphase
Answer:
Metaphase: During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate. Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate. ... These separated sister chromatids are known from this point forward as daughter chromosomes.

How does an organism obtain CO2, H2O, and energy
to undergo photosynthesis?
Answer:
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
Explanation:
By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2).

The correct answer is C. Gardeners choose which plants they let reproduced based on the plant traits.
Explanation:
In general, selective breeding involves the intervention of humans in the reproduction of species, this includes mainly plant and animal species. Moreover, in selective breeding, humans choose which specific species or individuals reproduce to favor certain traits. For example, a farmer might allow only the biggest cows to reproduce because this will lead to bigger calves. In this context, the option that shows selective breeding is C because this shows the intervention of humans in reproduction by selecting the individuals that will reproduce.
What differentiates Hela cells from other human cells?
Answer:
a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.
Explanation:
The main difference between Hela cells from other human cells is that a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.
What happens when the involvement of hela takes place?The involvement of hela made to the developing field of genetics is a lot was educated about cell reproduction, DNA and mapping genetics. The hela cells prepared them ideal for use in the polio vaccine trials because they were more liable than other cultured cells.
Cancer cells such as Hela cells escape to normal cell cycle by mutations that lead to the misexpression and/or overexpression of regulatory molecules (e.g., cyclins and cyclin-dependent kinases) and faulty checkpoint control of the cell cycle.
The control of the cell cycle depends on 1-cyclins and cyclin-dependent kinases (CDKs) that regulate the cell cycle by a cascade of protein phosphorylations and 2- a group of checkpoint controls that monitor the completion of critical cellular events.
Therefore, The main difference between Hela cells from other human cells is that a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.

How are government agencies like the local health department working to keep the public safe from the problem of HAB's?
Answer:
The local health departments work together with local water suppliers and act to monitor harmful algal blooms (HABs)
Explanation:
Harmful algal blooms (HABs) are produced by blooms of algae (phytoplankton), some of them may produce toxins that lead to illness/death in humans and marine organisms (e.g., marine mammals, fish, seabirds, etc). HABs represent a real concern for coastal areas. Cyanobacteria, also known as blue-green algae, may produce HABs both in fresh water and in marine water. Some of the most common causes that may lead to a HAB include the runoff of nutrients (especially those rich in nitrogen and phosphorus), high temperatures, a slow movement of water bodies, etc. The local health departments work to monitor these phenomena by collecting samples in order to analyze the state of the water (i.e., by identifying the presence of toxins, especially cyanotoxins) and give advice to local residents. For these purposes, it is generally required to analyze phytoplankton composition, especially the presence of accessory pigments to chlorophyll a (since these pigments represent good indicators for possible HABs).

Nucleotide are composed of a photosphate group a sugar and nitrogenous base DNA Isela made up of long Strands of nucleotide which part of the above molécule can differ between nucleotides
Answer:
The phosphate end and OH end of nucleotide in DNA differ from free nucleotides molecules.
Explanation:
5' phosphate group of one nucleotide and 3'-OH group of another nucleotide combine to form phosphodiester bond which holds the nucleotides in DNA molecule.
The phosphate end and OH end of nucleotide in DNA differ from free nucleotides molecules.

If a gene has two alleles, there are two possible genotypes.
a. True
b. False
Answer:
b. False
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
According to Mendel's Law of Dominance, if a gene has two alleles, there are three (3) possible genotypes.
The three (3) possible genotypes are;
I. A combination of alleles such as AA.
II. A dominant combination (phenotype) such as Aa.
III. A recessive combination such as aa.
Where;
A represents the dominant allelea represents the recessive allele.Also, a single version of a gene expressed by a living organism is referred to as an allele.

explain how the structure of ATP relates to its function
Answer:
ATP functions as the energy currency for cells. ... The structure of ATP is that of an RNA nucleotide with three phosphates attached. As ATP is used for energy, a phosphate group or two are detached, and either ADP or AMP is produced. Energy derived from glucose catabolism is used to convert ADP into ATP.

Why would cells from the same organism have different functions?
Answer:
Explanation: Cells have to fulfill multiple different functions to be able to build complex multicellular organisms. Differently expressed genes lead to different proteins made in the cell, which leads to different morphology, shape or function. ... When this factor cannot be expressed, these cells do not develop at all.

The current taxonomic system is based on the Linnaean classification system.
All of the current, living species in the world have been cataloged.
Answer:
1) taxonomy
2) species
3) the animal has sharp, pointed teeth
4) the current taxonomic system is based on the Linnaean system
5) he only had two kingdoms, animals and plants
Explanation:
did the quich check
The statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.
Taxonomy is a field of study focused on naming and classifying groups of organisms according to their morphological and genetic features. The taxonomic system organizes species from larger to more specific taxonomic categories in a hierarchical system.The botanical taxonomist Carolus Linnaeus is considered the father of taxonomy because he was the first person to formulate a system for classifying different species of plants and animals.Nowadays, the taxonomic system includes eight (8) categories from larger to more specific: domain, kingdom, phylum, class, order, family, genus, and species.In conclusion, the statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.
