An enzyme with Km = 3x10-4 M was tested with an initial substrate concentration of 10-6 M. Within one minute, 5% of the substrate had reacted. a) What percentage of substrate will have reacted in 5 min? b) If the initial concentration of substrate was 8x10-7 M, what percentage of substrate will have reacted in 5 min? c) Calculate Vmax. d) A concentration of 9x10-7 M, how long will it take for 50% of the substrate to react? e) A 10-6 M concentration, how long will it take for 75% of the substrate to react?
Answer:
[S] = 0.02 , Km = 1.2 x10^ -4 , rate = dP/dT = product formed per time = 2.7 x 10^ -6 moles /30 = 9 x10^ -8 we know rate = vmas

A ______occurs when the Earth casts a shadow that partially or fully covers the Moon
O lunar eclipse
O summer solstice
O solar eclipse
Answer:
Lunar eclipse
Explanation:
During a lunar eclipse, the earth enters between the sun and the moon, thus preventing sunlight from reaching the moon. There are two types of lunar eclipses: A total lunar eclipse occurs when the moon and the sun are on opposite sides of the earth. When only part of the earth's shadow covers the moon, a partial lunar eclipse will occur. In some cases, it is called a blood moon, similar to the blood moon that occurs this month.

Answer:
1. Kingdom Animalia
2. Yes
3. No
4. The taxonomic ranks get more specific as you go down the upside-down pyramid. As you go down the levels, the animals left are more similar but there is only one animal in the species category; the polar bear.
(Needs Two More Sentences)
1. Kingdom Animalia contains the greatest number of different organisms.
2. Yes, all organisms shown in the diagram that belong to the order also belong to the Phylum
3. No, all organisms shown that belong to the class Mammalia also below to the genus Ursus.
4. Ursus arctos—the brown or grizzly bear—is a species. It represents a separate genetic and physical group.
Diversity grows from species to kingdom. Animalia includes mammals, birds, reptiles, and more, including Ursus arctos. Multicellularity and heterotrophic feeding are common traits in the kingdom Animalia. From species (Ursus arctos) to kingdom (Animalia), organism diversity rises.

Different cell types in a multicellular organism contain the same genome, but differ in their patterns of gene expression.
A. True
B. False
Answer:
A
Explanation:
If a man has type B blood and his sister has type A blood, which combination listed below is most likely the genotypes of their parents?
Answer:
type AB father and type O mother
hope this helps! :D
The genotypes of the parents are type AB father and type O mother.
How is the blood type of a child determined?Each parent contributes to one of the two alleles to their child. A mother with blood type O can only pass allele O to her child. A father with type AB can pass either the A or B allele to the child. So the child can either have a genotype as AO or BO giving the child either A blood group or B blood group.
There are mainly eight blood genotypes. The blood types are determined by the location of A and B antigens and the presence of a protein called Rh factor.
Individuals with type O blood have no antigens attached to the cell surface of RBCs. It contains A and B antigens in the plasma portion of the blood. O blood type is needed the most for blood transfusion and blood donations.

The series of diagrams below represents a process carried out by a unicellular organism. This process is know as
Phagocytosis is a crucial mechanism by which cells engulf and absorb foreign substances. This method is how small, unicellular organisms like free-living amoebas obtain food. Thus, option B is correct.
What phagocytosis process carries by unicellular organism?Phagocytes, a type of living cell, devour or engulf other cells or particles through a process known as phagocytosis. An amoeba or other free-living single cell could make up the phagocyte, or it could be one of the body's cells, like a white blood cell.
In unicellular creatures, phagocytosis is a critical mechanism for nourishment; in multicellular organisms, it is a function of specialized cells called phagocytes.
Therefore, Phagocytosis is a process used by some single-celled protists, such as amoebae, to absorb food particles.

The true statement about how early humans met their needs is : ( A ) The first humans moved around alot looking for food .
Way of life of Early humansIn order to survive early humans moved around like nomads in search of food and shelter most of the times because there was no formal or mechanized way of cultivating agricultural products for food.
As humans continued to advance in knowledge they started farming and rearing of animals but these were not done by early humans.

Amino acids with hydrophobic R groups are most often found in the interior of folded proteins. true false
Answer:
True.
Explanation:
Amino acids with nonpolar, hydrophobic R groups combine together inside the protein, thereby making hydrophilic amino acid that is outside to interact with the water molecules that surrond it. The hydrophobic molecules tend to avoid water by coalescing to form an oily or waxy droplet. This then make hydrophobic and amino acids to come together in the interior of proteins, which is far from the aqueous environment.

Overfishing decreases the population of trout living in a river.
What would also decline because of the decreasing number of trout?
A mayflies that are part of the trout's diet
B. eels that compete with the trout for food
C. birds that use the trout as a source of food
D. fish that lay eggs that are eaten by the trout
Answer:
C. birds that use the trout as a source of food
Explanation:
Living organisms feed on one another in their natural environment in order to obtain energy for their various activities. According to this question, overfishing by humans decreases the population of trout living in a particular river.
This means that in that aquatic ecosystem (river), the population of organisms that feed on trout as a source of energy will also decrease. In this case, it is the birds. Hence, birds that use the trout as a source of food.
Answer:C
Explanation:
Because birds use that as a source of food.
