Answer:

1. Phil went to a movie with his friends - active voice

2. The peanut butter is being added

to the cake by the chef - passive voice

3. The blue dress had been put on

display by the store assistant - passive voice

4. Karl gave a touching speech at his

graduation ceremony - active voice

5. Jacob's party will be attended by

everyone in town - passive voice

6. Fred played with a monkey during

his first trip to a zoo - active voice

Explanation:

In English language, the voice of a sentence can either be passive or active.

A sentence is said to be ACTIVE if the subject is performing the action (verb). Hence, the sentence is referring to the subject doing the verb's action directly. For example;

1. Phil went to a movie with his friends

2. Karl gave a touching speech at his

graduation ceremony

3. Fred played with a monkey during

his first trip to a zoo

These are examples of sentences (1,2,3) in active voice because the subjects are performing the actions in the sentence.

On the contrary, a sentence is in the PASSIVE VOICE when the subject is acted upon by the verb in the sentence. In other words, the subject becomes the receiver of the veeb's action. For example;

4. The peanut butter is being added

to the cake by the chef

5. The blue dress had been put on

display by the store assistant

6. Jacob's party will be attended by

everyone in town

The above examples (4,5,6) are all in passive voices because the subjects in the sentences are acted upon by the verbs.

reverse transcription  

Explanation:

The central dogma of molecular biology states that the flow of the genetic information is unidirectional: DNA to RNA to protein. Thus, the central dogma indicates that a gene is always transcribed into a messenger RNA (mRNA) molecule, and then this mRNA is used as a template for protein synthesis during translation. Reverse transcription is an event that contradicts the central dogma since in this case there are enzymes known as reverse transcriptases that are capable of synthesizing DNA by using RNA as template. In eukaryotic cells, reverse transcription may occur naturally during the insertion of certain Transposable Elements (retrotransposons).

Answer:

This distribution of species supports Gleason´s Individualistic concept of a community.

Explanation:

This theory was proposed by Gleason and it states that plant species respond individually to environmental factors that continuously change at spatial and temporal levels. This means that the combination and distribution of plants in a certain point or area are unique because each vegetable species has a different distribution pattern and a different tolerance and abundance rate. Hence each species´ response curve to a certain gradient has its own shape and size and it different from other species curves.  

Plants assembly growing in an area is the result of environmental conditions and migration rate of species. As every area is continuously getting propagules of different species, the survival success of each plant depends not only in environmental factors, but also depends on the tolerance to other new species and their interactions. This combination along a gradient always results in different composition and abundance of species. This is why a sample can not be confined to a clearly defined vegetable community.

This point of view is known as individualistic or continuum concept of vegetable community. Gleason believed that vegetable species were distributed as a continuum and that communities can not be identified as combinations of associated species that repeat in space.

Answer:

mediante mutaciones en el ADN  

Explanation:

El desastre ecológico de Chernóbil estuvo asociado a la liberación de importantes cantidades de radiación en forma de radioisótopos hacia la atmósfera, como producto de la explosión de un reactor que contenía toneladas de uranio radiactivo. La exposición a este tipo de radiación aumenta las probabilidades de sufrir mutaciones en la molécula de ADN. Dicho de otro modo, la radiación incrementa las chances de sufrir cambios en el material genético hereditario. Las mutaciones generalmente son corregidas por los mecanismos de reparación del ADN; sin embargo, existen ocasiones donde las mutaciones no son reparadas. Por otro lado, las mutaciones a menudo tienen efectos deletéreos y por lo tanto están asociadas a enfermedades, ya que los cambios en la secuencia genética provocan consecuentemente también cambios en las proteínas codificadas por estos genes. Por ejemplo, las mutaciones sufridas por genes supresores de tumores se encuentran asociadas a la aparición de células cancerosas por el mal funcionamiento de dichos genes. El efecto de la mutación depende del tipo celular que sufre la mutación: aunque las mutaciones sufridas por células somáticas pueden afectar la salud, estos tipos de mutaciones no son heredadas (simplemente porque las células somáticas no se heredan), mientras que las mutaciones sufridas por células germinales, es decir, en las células encargadas de la formación de gametos, pueden ser transmitidas a la descendencia.

Answer:

The answer is below

Explanation:

The weight of trees is calculated using the equation:

[tex]W=b_o+b_1(D^2H)[/tex]

W is the tree weight in tons, D is the diameter of the tree in inches, H is the height of the tree in feet and [tex]b_o \ and\ b_1[/tex] are constants.

The circumference is given by:

Circumference = 2πr

Where r is the radius and 2r is the diameter

Therefore:

14 = 2(22/7)× r

14 = (22/7)×2r

2r= 14 × 7 / 22

Diameter = 2r = 4.455 inches

[tex]W=b_o+b_1(4.45^2*120)\\W = b_o+2381.643b_1\\Let\ us\ assume\ b_o = -35,b_1=1.9.\\Therefore\\W = -35+2381.643(1.9)\\W=4490 \ tons[/tex]

without atoms, the chemical elements wouldn't exist. then, molecules, then proteins, then life itself. basically we're made out of atoms just like everything else.

Explanation:

Answer:

The correct answer is urine with a lower concentration of sodium ions.

Explanation:

A hormone produced in the cortex or the outer section of the adrenal glands, which are located above the kidneys is known as aldosterone. The hormone plays an essential function in regulating the blood pressure primarily by functioning on the organs like colon and kidney to enhance the reabsorption of sodium or salt into the bloodstream and to enhance the concentration of potassium excreted in the urine.  

Along with sodium, the hormone also works to reabsorb more concentration of water, which further increases the volume of blood and thus the blood pressure. Therefore, with the increase in the levels of aldosterone, the kidneys generate urine with a lower concentration of sodium ions.  

In response to increased levels of aldosterone, the kidneys produce urine with a higher concentration of sodium ions. Therefore, option B is correct.

Aldosterone is a hormone produced by the adrenal glands, specifically in the zona glomerulosa of the adrenal cortex. It plays a crucial role in regulating sodium and potassium levels in the body.

When aldosterone levels increase, such as in response to low blood sodium levels or stimulation by the hormone angiotensin II. Then, it acts on the cells of the distal convoluted tubules and collecting ducts in the kidneys.

Answer:

Leading strand and Okazaki fragments

Explanation:

The two classes of DNA that the different samples represent include the leading strand and the Okazaki fragments.

The large molecules DNA with thousands/millions of nucleotides constitutes the leading strand of the DNA while the short stretches of DNA with just a few thousand nucleotides in light constitute the Okazaki fragments.

This is because, during replication, the leading strands of DNAs are usually synthesized in a continuous manner and end up forming a long, continuous daughter strand while the lagging strands are usually synthesized in short, discontinuous fragments known as the Okazaki fragments.

The continuous/discontinuous replication of the leading/lagging strands of the DNA is due to the characteristics of the enzyme responsible for adding bases to the growing daughter strands. The DNA polymerase enzyme can only add nucleotides in the 5' to ' direction.

Answer: Option A) Glucagon was secreted by his pancreas before he ate the cookies because blood glucose was low. Insulin was secreted after he ate the cookies because his blood glucose was high.

Explanation:When Kai was hungry and his blood glucose level was decreasing, glucagon is the hormone which was secreted by the islets of pancreas to increase the blood sugar levels in his body. Glucagon forces the liver to release the stored glucose in it, which increases the blood glucose level in the body. When Kai ate the sugar cookies there was enough of blood glucose available for his body, also it exceeded the requirement and went high. Insulin was then secreted to control this excess glucose from the islets of pancreas. As it helps the body cells to absorb the glucose and lowers the amount of glucose in the blood. It makes the cell available with the glucose to produce energy and perform their activities.

In short, glucagon and insulin both are secreted by the same organ which is islets of pancreas. But they differ in their function, glucagon increases the blood glucose when the body needs it, whereas insulin helps to absorb the excessive glucose and stores that in the body. Both are the hormones which help in regulating the body glucose levels.

During  process of digestion which takes place in digestive tract statement which describes role of glucagon and insulin is glucagon was secreted by  pancreas before he ate the cookies because his blood glucose was low. Insulin was secreted after he ate cookies because his blood glucose was high.

It consists of the gastrointestinal tract along with the accessory organs which are present in digestion process . It involves the breakdown of complex food into smaller components which can be easily assimilated and absorbed by the body.

The digestion process has 3 phases: cephalic phase , gastric phase and intestinal phase.Cephalic phase begins with secretion of gastric juices from gastric glands in response to sight and smell of food.It involves chewing and chemical breakdown of food by the action of digestive enzymes ,saliva in the mouth contain enzymes like lipase and amylase which are secreted by the salivary and serous glands present on the tongue.

Explanation:

Mendel crossed two unlike parents to get offspring with characterestics that differ that of the parents

Mendel used the characteristic of sexual reproduction in which the genes from the two parents combine to form the offspring. This results in offspring expressing the characteristics that differed from their parents.

Sexual reproduction is a type of reproduction in which the production of new organisms occur by the combination of genetic information of the two parents or individuals of different sexes. In most of the species, the genetic information is carried on the chromosomes in the nucleus of reproductive cells called gametes, which fuse to form a diploid zygote in the organism which matures to form a complete organism.

Mendel called the material which is responsible for the characteristics as "factors", and he proposed that during sexual reproduction, each of the parent contributed a form of this factor to the resulting offspring. This combination of the parental factors then determined which form of a trait will be visible in the offspring.
