Which light produces the most glucose in the plant? (remember from the previous lesson that glucose is a food product (sugar) made during photosynthesis in a plant.) blue green yellow red
Answer:
The correct answer is - red light.
Explanation:
Plants absorbed white light best than any other light, however, red light is better light than other lights after the white light due to its long wavelength and the right amount of energy to excite or stimulate the electrons of the light center of the chlorophyll and transit to a higher energy level which increases the rate of photosynthesis.
Red light is a light with a longer wavelength which helps in radiate and heat the chlorophyll than its counterpart. A high rate of photosynthesis results in more glucose production.
Answer:
Red light

An organism with a dominant allele for a particular form of a trait only exhibits the trait sometimes. Please select the best answer from the choices provided T F
Answer:
False. An organism with a dominant allele for a particular form of a trait always exhibits that trait.
Explanation:
According to Mendelian genetics, a dominant allele for a given characteristic will always be expressed in the phenotype, regardless of whether its allelic formula is with both dominant alleles or heterozygous.
In the heterozygous form, the dominant allele is able to avoid the expression of the recessive allele, expressing the phenotype. The recessive allele will only be visible in the genotype when both alleles in the pair are recessive.
In non-Mendelian inheritance, however, there are cases where the dominant allele is expressed in conjunction with another allele, such as co-dominance. In intermediate inheritance different alleles —dominant and recessive— are combined and expressed as a combined characteristic.
In the process of transcription, how does the mRNA strand relate to DNA?
a) The mRNA strand is complementary to the DNA strand; however, uracil instead of adenine is paired with thymine.
b) The mRNA strand is complementary to the DNA strand; however, uracil instead of thymine is paired with adenine.
c) The mRNA strand mimics the DNA strand; however, uracil is the 5th based used in the sequence.
d) The mRNA strand is an exact copy of the DNA strand.
b) the mRNA strand is complementary to the DNA strand; however, uracil instead of thymine is paired with adenine.
In the process of transcription, the mRNA strand is complementary to the DNA strand; however, uracil instead of thymine is paired with adenine.
TRANSCRIPTION:
Transcription is the first stage of gene expression which involves the synthesis of mRNA molecule from a DNA template. The double-stranded DNA molecule is separated and each single strand serves as a template for synthesizing a complementary mRNA strand. Adenine pairs Thymine while Guanine pairs with Cytosine in the DNA molecule but in the mRNA strand, uracil instead of thymine is paired with adenine. Therefore, in the process of transcription, the mRNA strand is complementary to the DNA strand; however, uracil instead of thymine is paired with adenine.Learn more at: https://brainly.com/question/9339389?referrer=searchResults

When animals feed off of land faster than the plants can regrow, the land is _______.
a.
below its carrying capacity
b.
forested
c.
overgrazed
d.
depleted
Answer:
C. Overgrazed
This is because there were too many animals on the land to feed, when there are to many animals grazing the same piece of land, it is called overgrazing.
Explanation:
When animals feed off the land faster than the plants can regrow, the land is called "overgrazed." Overgrazing is harmful for an ecosystem. It is caused by cows, goats, etc.
What is overgrazing?Grass is consumed by animals such as cows and goats. Due to overgrazing, the ecosystem is harmed. Due to overgrazing, the plantation of an area is affected. The plants cannot regrow early because they have been fed by animals. Due to the low plantation, it affects the ecosystem's rainfall.
Less transpiration by plants is the result of less rainfall. Hence, less precipitation is seen. The overgrazing causes soil erosion. Generally, soil is held by the roots of the plants. As plants are not there, soil can be easily erased by floods and other natural calamities. The soil erosion caused the land to become sterile. The crops won't grow on sterile land. The infiltration capacity of the soil is reduced.
Hence, the correct answer is "overgrazed." Option C is the correct answer.

Which are characteristics of all living things? Select three options.
grow and develop
make their own food
are made of many cells
respond to stimuli
can reproduce
Answer:
Grow and develop, respond to stimuli, and can reproduce
Explanation: The other random humans are wrong and I just did it on edge 2020
Answer:
The characteristics shared by all living things are that grow and develop, respond to stimuli and can reproduce.
Explanation:
Living things are different, and despite this, they have characteristics in common, since all are able to grow and develop, respond to external stimuli, and can reproduce themselves.
Growth and development: it is a process that occurs in stages and depends on the evolution of the form and functions of the organism.Response to stimuli: it is a function that is called relationship, through which an organism is able to perceive the stimuli of its environment and respond to them.Reproduction: this is the function in which other living beings with the same morphological and functional characteristics can be obtained from a living being.Making their own food and being made of many cells are characteristics that are not shared by all living things, since they correspond to autotrophic organisms and pluricellular organisms only, respectively.
Examine a two-gene cross that follows simple Mendelian inheritance of freckles and eyebrow shape between a woman with genotype Mmpp and a man with genotype mmpp. How many phenotypes are possible in their offspring and in what ratio?
a. 4 phenotypes: 9:3:3:1
b. 2 phenotypes; 1:1
c. 3 phenotypes; 8:4:4
d. 3 phenotypes; 1:2:1
The number of possible phenotypes in the Mendelian cross would be 2 in the ratio 1:1.
Phenotypic ratiosFirst, let us look at the result of crossing the two genotypes Mmpp and mmpp.
Mmpp will give the gametes Mp, Mp, mp, and mp
mmpp will give the gametes mp, mp, mp, and mp
The two sets of gametes can thus be lined up on both axes of the Punnet's square as shown in the attached image.
Genotypes of the offspring: 8 Mmpp and 8 mmpp
Since the two genes follow a simple Mendelian inheritance pattern, the 2 genotypes automatically equate to 2 phenotypes in the ratio 1:1.
Hence, the correct option is b.

write a 5 sentence paragraph that describes the characteristics that all living things share
Answer:
Living things are derived from single units and show several characteristics such as growth respiration, response to stimuli, homeostasis, evolution, and reproduction.
Explanation:
The natural world comprises several biotic or living and abiotic, non-living factors. Cells, are considered the smallest unit capable of supporting life. All living, or biotic factors must be able to grow, carry out respiration- a process that produces energy, and reproduce (pass on genes). They also show some level of organization or complexity, and respond to stimuli. Additionally, living organisms exhibit homeostasis or control over their internal environment and evolve or change over time to adapt to their external environments.
