What is breeding?breeding is a genetic concepts are applied in animal husbandry, agriculture, and horticulture. By selectively cultivating different plants, early farmers enhanced many of them. Pollination is the key component of modern plant reproduction, only the chosen male parent's pollen can be transported to the selected female parent.
There are three different breeds
Cross-breeding: mating between individuals from various breeds or lines. Pure breeding is the mating of members of the same breed or line. Inbreeding: When two relatives get together.Breeding is essential for improving traits that can improve the quality of life for people all around the world, including resilience to diseases and pests, drought, and temperature extremes.

Which of the following statements correctly describes cis-trans isomers?
A) They have variations in arrangement around a double bond.
B) They have an asymmetric carbon that makes them mirror images.
C) They have the same chemical properties.
D) They have different molecular formulas.
E) Their atoms and bonds are arranged in different sequences.
Answers
Answer: D
Explanation:
When both double-bond carbons are directly connected to a carbon and a hydrogen, cis-trans can happen. In this instance, a new isomer is produced by switching the substituent on one of the double-bond carbons. Thus, option D is correct.
What are the factor that affect cis-trans isomers?The molecule must restrict rotation. Each doubly bound carbon atom must have two nonidentical groups.
Molecules with the same atomic connectivity are what the cis isomers are known as. On the same side of the double bond, they stand in for comparable page groups.
Cis-trans isomers display a form of stereo isomerism, in which the atoms are arranged differently in three dimensions.
Therefore, On the other hand, trans isomers are made up of molecules with comparable side groups that are situated on the other side of the double bond.

suppose that you found out that a mating between a black animal and a brown animal produced all black offspring.Propose a hypothesis to explain the color of the offspring
Answers
If a mating between a black animal and a brown animal produced all black offspring, then the most likely hypothesis is that color is controlled by complete dominance and black animal parents are homozygous for this trait.
What is complete dominance?In genetics, complete dominance refers to the phenomenon for which one allele of a gene masks another allele of the same locus in order to express a given trait.
Therefore, with this data, we can see that complete dominance is caused when an allele masks the expression of the recessive allele in heterozygous individuals.

The law of _____ suggests that the orbit of planets is not circular but _____. Fill in the blanks: circles triangles ellipses rectangle
Answers
Answer:
Explanation:
Kepler's First Law: The orbit of a planet around the Sun (or a satellite around a planet) is not a perfect circle. It is an ellipse—a “flattened” circle. The Sun (or the center of the planet) occupies one focus of the ellipse. A focus is one of the two internal points that help determine the shape of an ellipse. The distance from one focus to any point on the ellipse and then back to the second focus is always the same.
The law of ellipses suggests that the orbit of planets is not circular but ellipses

This plant has one allele for axialflowers and one allele for terminal flowers.Based on this information, what is this pea plant's genotype for the flower position gene?axial flowersFfffterminal flowers
Answers
Axial flowers are in the middle of the plant's stem.
Terminal flowers are at the tip of the plant's stem.
The alleles that code for the trait "position of the flower" are F: axial flowers, and, f: terminal flowers.
A pea plant has axial flowers (Phenotype of the plant)
You know that it has one allele for axial flowers, F, and one allele for terminal flowers, f.

When we consider species like the ones the question tells us about, we usually one faces an example of predation, since squirrel can behave as tertiary consumers for spiders, which are then secondary consumers. So the roles they develop in the environment can be named as population maintenance (especially for the squirrels, because they can control the wolf spider population, and spiders can allow them to continue their population growth).
Why does the majority of photosynthesis occur in the leaves:1: roots are not exposed to sun since they are underground2: leaves contain chloroplasts which create store energy molecules3: all answers are correct
Answers
The correct option is 3.
The leaves have specific shapes that create the most efficient surface to absorb sunlight. Also, stomas are found mostly on the leaves, structures that allow the gas exchange: the CO2 enters into the leave, and O2 leaves it.
Photosynthesis, What goes in, What goes out, and Where within the cell does it occur?
Answers
Photosynthesis is the course where plants utilize sunlight, H20, and CO2 to build O2 and energy in the form of sugar.
In the course of photosynthesis, plants take in CO2 and H20 from the air and soil. Inside the plant cell, the H20 is degenerated or give up electrons, at the same time the CO2 is decreased or avails electrons. This converts the H20 into O2 and the C02 into glucose. The plant then discharges the O2 back into the air, and stock energy within the glucose molecules.
Photosynthesis takes place in small organelles called chloroplasts that stock the energy of sunlight. The chloroplasts contain the chlorophyll which is the primary pigment utilized in photosynthesis. The chloroplasts are enclosed by a double membrane and consist of a third inner membrane called thylakoid membrane that builds long folds within the organelle.
Answer - What goes in - CO2 and H20
What goes out - O2 and sugar
Where it occur - sunlight
The light reactions of photosynthesis takes place in the thylakoid membranes of the chloroplast. The light reactions catch energy from the sunlight which they alter to chemical energy and stock in molecules of NADPH and ATP.

a technologist is performing a body fluid analysis on a csf specimen recently received in the laboratory. four csf tubes were sent to the body fluids bench. the tech notices that all four specimens seem moderately blood tinged equally. moderate xanthochromia was also noted. what is the most likely reason for these findings?
Answers
The most common cause of xanthochromia, which manifests as a yellow, orange, or pink staining of the CSF, is the breakdown of haemoglobin into oxyhemoglobin, methemoglobin, and bilirubin as a result of RBC lysis.
Xanthochromic CSF: Is it typical?The yellowish staining of a centrifuged CSF specimen's supernatant is known as xanthochromia. It is abnormal and arises from the breakdown pigments oxyhemoglobin, bilirubin, and methemoglobin being released from RBC lysis into the CSF during Xanthochromia therapy. Treatment for xanthochromia entails addressing the underlying cause. If xanthochromia in the CSF indicates that the patient has a subarachnoid haemorrhage, they may have magnetic resonance imaging (MRI), CT angiography, or be sent immediately to the hospital for treatment.

A population's genetic makeup evolves throughout time as a result of the process of evolution. Adaptations made by organisms to their altering surroundings are reflected in evolution, which can lead to changed genes, unique features, and the emergence of new species. Both increases in genetic diversity and shifts in allele frequencies throughout time affect evolutionary processes. Experimentally, the evolutionary process from a "Big Bang" genesis to the protocell and from the advent of the protocell and a diversity of species to Darwin's mental capacity (mind) and society is being reexamined (The Descent of Man). The focus on endogenous ordering is one of studies' most fundamentally revisionary effects.
This concept has had a fresh influence on the notion of Darwinian evolution and has been discovered to apply to the whole sequence. It is well demonstrated in the orderly copolymerization of amino acids. I'll go through a few issues with handling the teaching of contentious themes in this section.

What is the difference between chromosomes, sister chromatids, non-sister chromatids, separated chromatids?
Answers
Chromosomes are structures of nucleic acids and protein carrying genetic information in the form of genes.
The chromosome is composed of two sister-chromatids.
During meiosis and mitosis, the sister chromatids are separated to separate half of the geentic material and create a new cell.
The difference between sister chromatids and non-sister chromatids is that sister chromatids have the same alleles in the same place and non-sister chromatids have different alleles in the same place. Non-sister chromatids will have the same length and configuration, but those different alleles will represent different types of the same characteristic (for example: different colors of fur). But they look the same as sister chromatids.

This waste gas is then transported by your bloodstream back to your lungs, where it is expelled after being eliminated from the bloodstream. Gas exchange, a crucial activity carried out automatically by your lungs and respiratory system, is a fundamental function.
How is gas exchange in the body?While carbon dioxide diffuses into the alveoli and is later breathed out of the body, oxygen diffuses from the alveoli into the capillaries, which carry it out of the lungs and to the rest of the body.
