O a. That migrating songbirds are better served by the farmer's coffee plantation
ob. That coffee beans have been grown under organic conditions.
Oc. That coffee quality is the best possible.
O d. That social equity has been improved for these farmers.

Answers

The correct answer is C. That coffee quality is the best possible.

Explanation

A cooperative is a term that refers to a society made up of several individuals who group for the common benefit of its members. These associations are organized democratically and are administered according to the agreement established by their partners. For example, in this case, the coffee producers formed a cooperative to sell their products directly to consumers and eliminate intermediaries. In addition, they were accredited with a social certification by an accredited agency, which supports their products by indicating to consumers that their coffee is of the best quality. Therefore, the correct answer is C. That coffee quality is the best possible.

Which of the following is not a characteristic of enzymes?
Each is used to break down substances.
Each has a specific substrate.
Each has an optimal temperature and pH.
O
Each has an active site.

Answers

Answer:

Each is used to break down substances.

Explanation:

Enzymes merely speed up a chemical reaction, not necessarily break down substances.

Each enzyme is used to break down substances is not a characteristic of enzymes. The correct option is A.

Thus, enzymes aren't just utilized to degrade things. Enzymes perform additional crucial tasks in addition to being essential for the breakdown (catabolism) of substances. In living things, enzymes operate as biological catalysts to quicken chemical processes.

Enzymes achieve this by reducing the activation energy needed for a reaction to happen and thereby speeding up the reaction rate. While some enzymes are engaged in the breakdown of chemicals, others are involved in the synthesis or modification of other molecules (anabolism).

Thus, the ideal selection is option A.

In cats, coat color is an X-linked trait with incomplete dominance. Yellow coat is caused by the allele XT and black coat by the allele Xt. A tortoise cost is caused by the heterozygous condition. What is the correct way to represent the genotype of a male cat with a black coat

Answers

Answer:

The genotype of a black male is XtY

Explanation:

Available data:

coat color is an X-linked trait with incomplete dominance.Yellow coat is caused by the allele XTBlack coat by the allele Xt.Tortoise coat is caused by the heterozygous condition

So,

females genotypes           females phenotype

  XTXT                →        Yellow coat   XtXt                  →         Black coat   XTXt                 →         Tortoise coat

males genotype                    males phenotype

  XTY                   →         Yellow coat   XtY                    →         Black coat

Males only carry one X chromosome, so they can only be either black - XtY- or yellow -XTY-.

Females are the only ones that can express the tortoise coat.

The correct way to represent the genotype of a male cat with a black coat - XtY

We know that,

In cats, coat color is an X-linked trait - it means it is influenced by the X allele onlyIn cats, coat color is shows incomplete dominance - it means if corresponding alleles present together they will show an intermediate coat color.the allele XT - Yellow coatthe allele Xt - black coatXTXt (heterozygous) - tortoise coat (incomplete dominance)In X linked traits heterozygous conditions are not possible in males as they have only one X allele and the other is Y allele.

So,

Female cats genotype would be:

XTXT - female cat with yellow coatXTXt - female cat with a black coatXtXt - female cat with tortoise coat

Male cats genotype:

1. XtY - black coat male cat

2. XTY - yellow coat male cat.

Thus, The correct way to represent the genotype of a male cat with a black coat - XtY

©2021 Illuminate Education Inc.

Answers

Answer:

hmm

Explanation:

On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.

Plausible solution to human activities contributing to increasing amounts of carbon dioxide(carbon emission) in the atmosphere are :

Use only alternative energies for the production of electricity
Require all new automobiles manufactured to run on electricity rather than gasoline.
Plant more trees and decrease deforestation practices so that more carbon dioxide can be absorbed from the atmosphere.
Require everybody to use mass transportation or methods of transportation that do not require burning fossil fuels, such as riding bicycles.

What is carbon emission ?

Carbon emission (greenhouse gas emissions) from human activities strengthen the greenhouse effect, causing climate change. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution.

Alternative energy is energy that is collected from renewable resources that are naturally replenished on a human timescale, hence contributing to betterment of environment.
Electric automobiles do not cause carbon emission.
Trees absorb the carbon dioxide from the environment and release oxygen.
Mass transportation will cut the cut out the percentage of carbon emission by several folds.

A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPa, E for the epoxy is 2.4 GPa. Find the elastic modulus of a composite that contains 5% fibers in the longitudinal direction, Ecl

Answers

Answer: hello your question is in complete  below is the complete question

A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPA, E for the epoxy is 2.4 GPa. Find the elastic modulus of a composite that contains 5% fibers in the longitudinal direction, Ecl = ViEi + EmVm? (note Vi + Vm= 1.) O 5.88 GPa O 5.66 GPa O 2.52 GPa O 6.74 GPa

answer : 5.88 GPa

Explanation:

Fiber reinforced composite containing e-glass fibers

E for the glass ( Ei ) = 72 GPa

E for the epoxy ( Em ) = 2.4 GPa

Determine the Elastic modulus of a composite containing 5% fibers

percentage of glass = 5% = Vi = 0.05

∴ percentage of epoxy = 95% ; Vm = 0.95

using the relation included in the question

Ecl = Ei Vi + Em Vm

    = ( 72 * 0.05 ) + ( 2.4 * 0.95 )

    =  3.6 + 2.28  = 5.88 GPa
