How does independent assortment increase genetic variation in Meiosis?
Answer:
Independent assortment produce new combinations of alleles.
Explanation:
In meiosis I, crossing over during prophase and independent assortment during anaphase creates sets of chromosomes with new combinations of alleles. Genetic variation is also introduced by random fertilization of the gametes produced by meiosis. It results in gametes that have unique combinations of chromosomes.
A certain sugar has no change in color when tested with Benedict’s solution. Can you tell what type of sugar it is? Explain.
Answer:
a certain sugar has no change in color when tested with benedict solution. can you tell which saccharide it is? no because it could be poly or disaccharide. what is the chemical formula for a polysaccharide molecule that contains 4 glucose molecules?
Sucrose
Sucrose (table sugar) contains two sugars (fructose and glucose) joined by their glycosidic bond in such a way as to prevent the glucose undergoing isomerization to an aldehyde, or fructose to alpha-hydroxy-ketone form. Sucrose is thus a non-reducing sugar which does not react with Benedict's reagent.
Explanation:
Sugars which give no color in Benedicts test are non-reducing sugars. Sucrose, a non reducing sugar does not undergo a color change in Benedict's test.
What is Benedict's solution?Benedict's solution is a chemical reagent containing copper sulphate pentahydrate and mixtures of sodium carbonate and sodium citrate. It is used to test the presence of reducing sugars.
A positive Benedicts test gives color change of blue to brick red precipitate whereas, non-reducing sugars does not give a positive result.
Sucrose contain fructose and glucose, they do not reduces the copper ion in Benedict's solution because there are no free aldehydes or ketones in sucrose.
Thus, sucrose does not reduce and will not give a color change in Benedict's test.

what type of immunity can be transferred by bodily fluids from one person to another, thus conferring immunity to the recipient?
Why does a plant produce more sugar after summer?
Answer:
Sunlight = Energy
Explanation:
Plants have chlorophyll that uses sunlight from the sun to create energy.
The energy is then used to change carbon dioxide from the air into sugars like glucose. The plant transports sugars into the tissues like roots, flowers and fruits so it can grow.
Answer:
Plants have chlorophyll that uses sunlight to gather energy. The energy is then used to change carbon dioxide from the air into sugars like glucose and fructose. ... They transport sugars throughout the plant and supply it to tissues like roots, flowers and fruits that depend on this sugar to grow.

5. The human immune system is a complex network of cells and organs that evolved
to fight off infectious pathogens. Vaccines teach the immune system by mimicking
a natural infection. The influenza vaccine, contains a weakened form of the virus
that doesn't cause severe disease or reproduce very well. Human white blood cells
(WBC's ) can't tell that the vaccine viruses are weakened, so they kill the viruses.
Antibody levels start to decline over time and the influenza virus evolves very
rapidly. Why does and individual need to get a yearly flu vaccine?
Answer:
the flu virus mutates to different form so updating the vaccine is helpful

which combination of cells and growth factors would serve as the control group?
Answer:
These stimuli, called growth factors, are naturally occurring proteins specific to certain groups of cells in the body. They include nerve growth factor, epidermal growth factor, and platelet-derived growth factor.
Explanation:
Hope this helps.
Growth factors are defined as the proteins that bind to specific receptors, which activate the cascade of signal transductions. The growth factors lead to proliferation, apoptosis, and development.
Different types of growth factors stimulating the signal transduction are:
1. Nerve growth factor is controlled by the gene NGF. It provides the instructions to make the beta protein, which is important for the survival and development of the nerve cell.
2. Epidermal Growth Factor is a type of factor that stimulates cell development and cell proliferation. It generally stimulates the fibroblasts and epithelial cells.
3. Platelet-derived growth factor regulates cell division and growth. These factors help in healing and repairing the wound and walls of the damaged blood vessels.
Thus, the growth factors when bound to specific cell receptors control the various activities of the cells.

Which of the following statements accurately describes the relationship between photosynthesis and cellular respiration?
The function of photosynthesis is to use solar energy to make ATP; the primary function of respiration is to break down ATP to release energy.
Photosynthesis only occurs in heterotrophs, while cellular respiration only occurs in autotrophs.
Photosynthesis and cellular respiration occur in separate, specialized organelles, and the two processes cannot occur in the same cell at the same time.
Photosynthesis uses solar energy to create organic molecules; cellular respiration breaks down organic molecules to make ATP.
Answer: The function of photosynthesis is to use solar energy to make ATP; the primary function of respiration is to break down ATP to release energy.

Answer:Madagascar Pochards
Explanation: The Madagascar Pochard, or sometimes known as the Madagascan pochard, is a very rare diving duck of the genus Aythya. Thought to be extinct in the late 1990s, individuals of the species were recovered in 2006 near Bemanevika, Madagascar, at Lake Matsaborimena. The species is only found in Madagascar's interior marshes, where it is endemic. The sole wild populations are currently found in Lake Sofia and Lake Matsaborimena. Meanwhile, there are slightly over 50 pochards at Bemanevika.

Stella described protein synthesis as a process that makes the necessary proteins for the human body to function. She
explained the process in the following steps.
1. DNA is transcribed into mRNA.
2. Amino acids form a chain.
3. The amino acid chain is folded into a protein in the endoplasmic reticulum.
What step did Stella miss in her explanation?
(1 point)
O Polypeptide chains express gene traits.
O tRNA delivers the DNA to the ribosome.
hy
O DNA is replicated into two daughter cells.
O mRNA is translated into amino acids.
The step of protein synthesis missed by Stella would be the translation of mRNA into amino acids.
The process of protein synthesis can essentially be divided into 2, namely:
TranscriptionTranslationDuring transcription, genetic information on DNA is transcribed into mRNA. Once this is done, the genetic codes in mRNA are then translated to their respective amino acids and linked by peptide bonds.
The polypeptide bond undergoes further processing such as folding in the endoplasmic reticulum.
Thus, before amino acids can form a polypeptide chain, they must first be translated from genetic codes in mRNA.

Modern taxonomy can be used to distinguish how closely related organisms are. It is a branch of systematics used to classify organisms based on different phenotypic traits and characteristics.
Taxonomy is a system of identifying and classifying biological systems.
Modern taxonomy refers to the system of classification of organisms on the basis of their evolutionary relationships (i.e., its basis involves phylogeny).
Modern taxonomy takes into consideration empirical evidence from different fields of study (e.g., morphology, cytology, physiology, etc).

The three ecosystem services that insects provide are dung burial, pest control, and pollination.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
