Incomplete dominance
O polygenic recessive

Answers

Answer: Polygenic recessive

Explanation: Because polygenic dominance describes a relationship between the alleles of a polygenic trait where some alleles are dominant and others are recessive.

This is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).

What is Polygenic inheritance?

Polygenic inheritance can be described as the inheritance of traits that are governed by different genes and not just a single gene, and can also be referred to as non-Mendelian inheritance, where traits run like a bell. distributes the sizes and shows the different combinations such as dominant and recessive alleles.

Polygenic traits express several different phenotypes, or displayed characteristics where this inheritance is a type of incomplete dominance inheritance, where the expressed phenotype is a mixture of inherited traits.

Thus, this is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).

3. evergreens are plants that maintain their leaves in all seasons and include trees such as ---, ---, and ---.

4. hardwoods reproduce using flowers and have broad leaves; hardwoods include trees such as ---, ---, and ---.

Answer:

1. deciduous trees lose their leaves seasonally and include trees such as elm and maple.

2. conifer leaves are generally thin and needle-like, while seeds are contained in cones. conifers include pine and cedar.

3. evergreens are plants that maintain their leaves in all seasons and include trees such as Pine, Cedar, and Mango.

Explanation:    

Deciduous trees:  These plant species lose their leaves every year during the cold and dry autumns and winters, as it is the most limiting period over the year. Foliage resprout again during the warmer wet season when it rains more often, during spring and summer. Template forest biome characterizes for having deciduous trees such as oaks, maple, or elm, among other phanerophyte species.

1. deciduous trees lose their leaves seasonally and include trees such as elm and maple.

Conifer: Correspond to the gymnosperm group. They are perennial, vascular, evergreen, woody plants. They characterize for having a straight trunk with secondary growth and no vessels in the xylem tissue. Their branches usually develop horizontally, with needle-like leaves growing on them, unisexual flowers, and seeds included in a cone.

 2. conifer leaves are generally thin and needle-like, while seeds are contained in cones. conifers include pine and cedar.

Evergreens: Perennial plants that keep their green leaves the whole year.  These are the opposite of the deciduous trees. Tropical forests characterized for having these broadleaf plant species, such as mango, that are favored by the environmental conditions as precipitations are abundant and the average temperature is elevated most of the year. Also, many evergreen plants are typical of the boreal forest.  Pines, cypress, cedar, and sequoia are examples of these last ones.

3. evergreens are plants that maintain their leaves in all seasons and include trees such as Pine, Cedar, and Mango.

Hardwoods: Angiosperms. Xylem with vessels. These species present a high diversity in shape, textures, and sizes. They might reproduce asexually or sexually by producing flowers, fruits, and seeds. Also, they might be either evergreen or deciduous.

4. hardwoods reproduce using flowers and have broad leaves; hardwoods include trees such as Elm, Maple, and Mango.

When ATP levels fall ________ binds to ________of ____________. This interaction leads to an increase of cellular ___________ , so that this is a n example of a ___________ feedback loop.

Answers

Answer:

Explanation:

The rate limiting reaction of aerobic respiration involves the phosphorylation of fructose phosphate by the enzyme phosphofructokinase. The rate at which this enzyme makes product is [increased, decreased] when ATP levels rise because the molecule ATP binds to an allosteric site on the enzyme and acts as a direct inhibitor. When ATP levels fall AMP binds to the allosteric site of phosphofructokinase. This interaction leads to an increase of cellular ATP, so that this is an example of a negative feedback loop.

The rate limiting reaction of aerobic respiration involves the phosphorylation of fructose phosphate by the enzyme phosphofructokinase. The rate at which this enzyme makes product is decreased when adenosine triphosphate (ATP) levels rise because the molecule adenosine triphosphate (ATP) binds to an allosteric site on the enzyme and acts as a direct inhibitor. When adenosine triphosphate (ATP) levels fall, AMP binds to the allosteric site of phosphofructokinase. This interaction leads to an increase of cellular adenosine triphosphate (ATP), so that this is an example of a negative feedback loop.

What is an aerobic respiration?

An aerobic respiration can be defined as a chemical and biological process that involves the use of oxygen in living organisms to make energy (ATP) from carbohydrates (sugars) during cellular respiration.

This ultimately implies that, an aerobic respiration can take place or occur in the presence of oxygen.

What is an enzyme?

An enzyme can be defined as a biological catalyst that typically speeds up (accelerates) the rate of a chemical reaction, especially by lowering the activation energy of its chemical reactants.

Factors that affects an enzyme

There are four (4) main factors that affect the actions and the rate of an enzyme and these include the following:

Answers

Answer:

The substrate molecules are entering the cells, so no product is made yet.

There is sufficient substrate, so the reaction is proceeding at a maximum rate

As the substrate is used up, the rate decreases (the slope is less steep)

The line is flat because no new substrate remains and thus no new product appears

Explanation:

First the substrate molecules enters in the cell and no product is produced because the reaction is not started yet. When the reaction starts, the substrate is in large amount while on the other hand, the amount of product is low. As the reaction proceed forward, concentration of substrate is lowering and concentration of product is increasing. When all the substrate used up, so no new product is formed.

What is your opinion on the use of stem cells, obtained from fertilized eggs or early stage embryos

Answers

I believe that it can help in the future. Who knows embryonic stem cells may lead to new, and more effective treatments for serious human ailments and alleviate the suffering of thousands of people!

USE OF STEM CELL:

The first attempts to turn mature cells back into pluripotent stem cells involved a process called cloning. In the cloning process, an egg is fertilized in the lab, and right after fertilization, the DNA is removed from the egg.These stem cells come from embryos that are three to five days old. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.Despite the potential benefit of using human ES cells in the treatment of disease, their use remains controversial because of their derivation from early embryos.

Answers

Answer: the 1st one

Explanation:

A grassland predator and prey, such as a cheetah and a zebra. Therefore correct option is (A).

What organisms have common adaptations?

The pair of organisms that is most likely to have adaptations in common is a pair of organisms that share similar environmental pressures or ecological niches. Organisms that occupy similar habitats, have similar diets, or face similar challenges are more likely to evolve similar adaptations over time.

For example, predatory animals such as lions, tigers, and leopards have evolved similar adaptations such as sharp claws, powerful jaws, and keen senses to help them catch prey. Similarly, desert-dwelling animals such as camels, kangaroo rats, and fennec foxes have adaptations such as the ability to conserve water, tolerate heat, and dig burrows in sandy soil to survive in their arid environments.

Answers

Answer:

D all of the above

Explanation:

just took the test

Environmental manipulation can have both types of consequences - beneficial as well as adverse. At times, these changes can be unexpected too. The correct option is D.

What negative effect does environmental manipulation of a crop have?

The crop can have a need for more water as compared to the original if there would be a change in the soil, region or even climate of the crop. An increase in the temperature can affect the availability of water to the crop.

Changes in the soil can result in variation in the availability of minerals required for the growth of plants. This can cause improper health condition of the crop, which will ultimately decrease its yield.

Overuse of fertilizers and pesticides can affect the quality of the soil and also have a negative impact on the crop. It can also be passed on to the consumers of the crop due to bioaccumulation.

Thus, all of the mentioned statements are correct. Hence, the correct option is D.
