Answer:

30% of the total carbohydrates for a person on a 2,000 calorie diet

Explanation:

Study Island

30% of the total carbohydrates for a person on a 2,000 calorie diet will provide if drinking 16 oz of this beverage.

The table is based on 2000 calories, and one serving is 8 oz.

Thus the question is for two servings.

Which equals 30% carb of a 2k calorie diet.

Thus, we can conclude that option D is the correct option, 30% of the total carbohydrates for a person on a 2,000 calorie diet.

Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

A. mRNA carries copies of instruction to make proteins from the DNA to the rest of the cell.

mRNA is transcribed from DNA, then translated by the ribosomes into a polypeptide chain (protein)

Answer: cell membrane - the thin layer of protein and fat that surrounds the amoeba; it allows some substances to pass into the cell, and blocks other substances.

Explanation:

Answer:

The plasma membrane of a cell is a network of lipids and proteins that forms the boundary between a cell's contents and the outside of the cell.

Answer:

Answer:

The correct answer is - deals with the motion of an object without or with the reference of force.

Explanation:

The mechanism is the branch of sciences that deals with an object in a motion under the reference force or the object that remains at rest. This branch of physics leads to topics of gravitational force, electricity, quant, or magnetism according to the nature of the forces involved.

Modeling, aerodynamics, and all other applications of mechanics required the use of laws of newton, the formula of mathematics, and algebra.

Answer:

blood glucose

Explanation:

Constants never change.

Controls typically don't change or they are done by standard means

(like in an experiment where you water plants with sodas, the plant you use water with is the control)

Dependent variables are the outcome of the experiment. This is the result of changing something.

Independent variables are what you are testing. A independent variable is something that is  intentionally altered.

easy way to remember it is that dependent variables depend on what other variables are. so you cant change a dependent variable, but you can change the other variables.

Answer:

Active

Explanation:

Endocytosis is a type of active transport where large molecules or even cells are moved inside the cell.

Answer:

from the intermembrane space to the matrix

Explanation:

In the electron transport chain (ETC), electrons flow from one protein complex to another. However, as this electrons are transfered, protons (H+) is built up from the intermembrane space of the mitochondria to the mitochondrial matrix.

Hence, according to this question, a proton gradient is formed when hydrogen ions (H+) are moving from the intermembrane space to the matrix of the mitochondrial.

Explanation: it is a Decomposer a Predator and a and it is a Consumer

The one that does not describe the newly discovered fish is "producer," which is the third option, as producers are organisms that can produce their own food through photosynthesis or chemosynthesis.

Producers are organisms that can synthesize their own organic molecules from inorganic substances using energy from the environment, such as sunlight or chemical energy. This process is known as photosynthesis or chemosynthesis, depending on the source of energy used. Examples of producers include plants, algae, and some types of bacteria, while on the other hand, consumers are organisms that obtain their energy and nutrients by consuming other organisms. Consumers can be classified into different types based on their feeding habits.

Hence, the one that does not describe the newly discovered fish is Producer, which is the third option.

Answer:

Platyhelminthes

Explanation:

Platyhelminthes (phylum Platyhelminthes), also known as flatworms, are bilaterian, unsegmented and soft-bodied invertebrates. Platyhelminthes are hermaphroditic organisms with internal fertilization. In addition, this group shows a series of characteristics including 1-a ladder-like nervous system, 2-presence of parenchyma in the body cavity, and 3-flame cells, i.e., specialized excretory cells that function like a kidney. Platyhelminthes can be divided into three groups: Turbellaria (generally found in freshwater), Trematoda (generally parasitic), and Cercomeromorpha (exclusively parasitic).

Answer:

The transgene could be silenced by: 1- epigenetic mechanisms (e.g., DNA methylation, histone deacetylation, etc.), and 2-the RNA interference (RNAi) pathway

Explanation:

Epigenetics refers to the heritable changes caused by the activation and deactivation of genes without changing the DNA sequence. Epigenetic mechanisms include 1-DNA methylation on cytosine residues, and 2-modifications on amino acids in the tails of histone proteins (e.g., methylation, acetylation, ribosylation, phosphorylation, etc). These two epigenetic mechanisms can modify DNA structure and thus alter the accessibility of transcription factors, thereby suppressing gene/transgene expression. Moreover, the RNA interference pathway (RNAi) is a naturally occurring mechanism capable of suppressing gene/transgene expression both at transcriptional and post-transcriptional levels. The RNAi mechanism is triggered by regulatory non-coding RNAs (ncRNAs) such as, among others, long non-coding RNAs (lncRNAs) and small ncRNAs (e.g., miRNAs, piRNAs, siRNAs, etc). In this case, for example, DNA methylation on promoter sequences could suppress transgene expression, thereby methods to measure DNA methylation can be used to test this possibility (e.g., bisulfite genomic sequencing). Moreover, miRNAs that bind to the messenger RNA of the transgene could also inhibit its expression by triggering the RNAi pathway (e.g., mRNA degradation), thereby methods to measure mRNA levels can be used to test this possibility (e.g., RT-PCR).

Answer:

In the mid-1800s, over-hunting of Northern Elephant Seals reduced their population size to fewer than 40 individuals. However, the population has since rebounded to over 100,000 animals. The population went through a _bottle neck event (genetic drift)_, which makes it more susceptible to _developing a genetic disease_.

Explanation:

Genetic drift is the random change that occurs in the allelic frequency of a population through generations. The magnitude of this change is inversely related to the size of the original population. These changes produced by genetic drift accumulate in time. Eventually, some alleles get lost, while some others might set. Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure-bottleneck effect- or because of a population split -founder effect- . The bottleneck effect most likely affects smaller populations.  

In the exposed example, extensive hunting acted as a pressure that reduced the number of Northern elephant seals to fewer than 100. This population experienced one or many generations of small size since these animals were affected by hunting. As the survivors did not have the whole genetic pool of the original population, the population size might have recovered to a current population size of 100,000 individuals, but the genetic pool might have not. When the small population increases in size, it will have a genetically different composition from the original one. In these situations, there is a reduced genetic variability, with a possibility of developing a peculiar allelic component. If the survivors in the population carried or developed a mutation, probably this mutation passed from generation to generation. It will involve more individuals each time and increase the probability of developing a genetic disease.

Answer:

The correct answer is - 7 cc or ml.

Explanation:

Given:

The volume of water in a graduated cylinder = 30 mL

The volume of rock = ?

Final volume = 37 ml

Formula:

If an object is placed in water, then the amount of water that is displaced or increased by submerging the object is equal to the volume of the object.

Vi + Vo = Vf

Vi = initial volume

Vo = volume of object

Vf = final volume

Solution:

Placing the values in formula -

30 + Vo = 37

Vo = 37 - 30

Vo = 7 ml or cc.
