Answer:
amylase and other carbohydrase enzymes
In clover plants, the pattern on the leaves is determined by a single gene with multiple alleles that are related in a dominance series. The gene is not pleiotropic. Seven different alleles of this gene are known; an allele that determines the absence of a pattern is recessive to the other six alleles, each of which produces a different pattern All heterozygous combinations of alleles show complete dominance
a. How many different kinds of leaf patterns (including the absence of a pattern) are possible in a population of clover plants in which all seven alleles are represented? phenotype that could be represented by only a single genotype? you can identify a few plants representative of all possible pattern types. Explain this finding.
b. What is the largest number of different genotypes that could be associated with any one phenotype? Is there any
c. In a particular field, you find that the large majority of clover plants lack a pattern on their leaves, even though you can identify a few plants representative of all possible pattern types.explain this finding
Answer:
The correct answer is -
a. 7
b. 7 (p1p1, p1p2, p1p3, p1p4, p1p5, etc
c. p7 is abundant
Explanation:
According the question the dominance of the big leaves is p7 > p6 >p5 >p4 >p3 >p2 >p1 where 1 represent least dominance and 7 represent most dominance
let represent the phenotype with the numbers 1 to 7 and genotype with a combination of these numbers so the genotype in respect of phenotype would be :
p7p7,p7p6, p7p5, p7p4, p7p3, p7p2, p7p1 - most dominant 7
p6p6, p6p5, p6p4, p6p3, p6p2, p6p1 - 6
p5p5, p5p4, p5p3, p5p2, p5p1 - 5
p4p4, p4p3, p4p2, p4p1 - 4
p3p3, p3p2, p3p1 - 3
p2p2, p2p1 - 2
p1p1- 1 least dominant
Thus, there are 28 different combinations or patterns of genotypes. 7 phenotypes patterns.

Brainstorm ideas for ways people could use sunflowers to reduce soil contamination by heavy metals?
I need help
Answer:
Seeds are being delivered to every mailbox in town, all in hopes of purifying the soil using a technique called phytoremediation.Sunflowers can absorb many different toxins and chemicals from the soil and then store those chemicals at the cellular level. Once they're absorbed, they won't leach back out again.

Describe how water forms hydrogen bonds and describe one specific
property of water that results from hydrogen bonds.
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.
Compare mitotic and post-mitotic cells (define, give example of each).
Answer:
Mitosis is a process where a single cell divides into two identical daughter cell.
EXAMPLE ----- the way the skin cells covering a child's body all multiple when they are growing.
A mature terminally differentiated (TD) cell no longer able to undergo mitosis is defined as post mitotic cells.
EXAMPLE-------- mature neurons and mature multiple cells.

Whilst bushwalking, Brian begins to feel chafing sensation in his thighs. In order to perceive this chafing, neural impulses must travel in one direction – from his (skeletal muscle, skin, brain, spinal cord) to his (brain, skin, spinal cord, skeletal muscle) This information would travel via (GVE,GVA,GSA,GSE) neurones.
WHICH ONE OF THE OPTIONS IN THE BRACKET
Answer: Skin; Brain, GSA - General Somatic Afferent
Explanation:
Whilst bushwalking, Brian begins to feel chafing sensation in his thighs. In order to perceive this chafing, neural impulses must travel in one direction – from his skin to his brain. This information would travel via GSA neurones.
The peripheral mechanoreceptors which are found on the skin and used to detect movement will detect the chafing and send it to the brain.
This information will be received by the brain through General Somatic Afferent neurons which are spread across the body and have the primary function of detecting touch and temperature.
Eukuaryotic cells are different from prokaryotic cells because eukaryotic cells
Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.

One trait a plant can have is either red leaves (R) or brown leaves (r). Another
trait is tall stems (T) or short stems (t). A plant used in a dihybrid cross has
the genotype RrTt. What is the phenotype of this plant?
Answer:
its phenotype will be such that:
·It will have red leaves
·and tall stem.
Explanation:
As red leaves R is dominent allele and tall stem T is also.So the red colour of leaves and tallness of stem will be the dominent traits.
Practically speaking, how would you determine that Na + influx into a cell underlies the early current? Group of answer choices Remove Na + from the extracellular compartment and assess the early current under new conditions. Use the voltage clamp method to measure the current. Remove K + from the intracellular compartment and assess the early current under the new conditions. Treat the cell with tetraethylammonium. Replace intracellular Na + with its radioactive form and trace its movement across the membrane.
Answer:
Remove Na + from the extracellular compartment and assess the early current under new conditions
Explanation:
Na+ is a critical ion that influences the action potential in nerve cells. During the transmission of an impulse, the cell membrane is open so ions can flow through it, i.e., positively charged ions such as sodium ions (Na +) move within the cell, while negatively charged ions move outside the cell. This process produces a change in the action potential by rapidly increasing the positive charge in the nerve fiber, being thus the impulse propagated when this charge reaches +40 mv. In consequence, the effects of Na + on the single-channel current can be analyzed by removing positive ions and determining the change in the reversal potential of this channel.
How did Louis Pasteur help disprove spontaneous generation?

Explanation:
In pea plants, flower color is controlled by a pair of alleles where purple (P) is dominant to white (p). Stem length is controlled by another pair of alleles where tall (T) is dominant to short (t). These two allele pairs segregate independently. Suppose you have a pea plant that has purple flowers and tall stems and you wish to carry out a testcross in order to determine its genotype. Complete the predictions using the correct terms.

Which of the following forests contains 50% of terrestrial plants and animal species?
Answer:
This question lacks options, they are:
a)Cold forest
b)Tropical forest
c)Temperate forest
d)Cloud forest
e)Alpine forest
The answer is B. Tropical forest
Explanation:
Tropical forest is one of the forests found in nature. The tropical forest receives the best environmental conditions in terms of vegetation growth. Hence, it is said to contain the most diverse organisms in nature. This means that tropical forests holds more species of terrestrial organisms than any other forest or biome.
Therefore, tropical forests are believed to contain 50% of the Earth's terrestrial plants and animal species due to their biodiversity richness.
