Can someone help me with my my anatomy homework

Answer:

The correct answer is option a. "7.1".

Explanation:

One easy way to determine if a peptide sequence is acidic, basic or neutral is to check for the number of amino acid residues that are acidic, basic or neutral. In this case, most amino acid residues are neutral, which mean that under neutral conditions they have a pKa close to 7.0. Particularly, the content of 3 leucine, 2 alanine and 2 glycine residues determines that the peptide have a pI of around 7.1.

Answer:

Precipitation

Explanation:

The process which is driven by gravity is precipitation. In the process of precipitation, the clouds formed by evaporation of water drops off in the form of rain. Thus, the correct option is 3.

Precipitation is one of the main processes of water cycle. Water cycle is a biogeochemical cycle which involves the flow of water in the atmosphere through different processes such as evaporation, precipitation, and in different phases such as solids, liquids, and vapors.

Precipitation is the process of water cycle in which the clouds formed by the evaporation of water drops off back to the land in the form of rain. This process is driven by the influence of gravitational force.

Therefore, the correct option is 3.

The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.

Answer:

Smooth cartilage prevents friction as the bones move against one another. in freely moveable joints, the entire joint is enclosed inside a membrane filled with lubricating synovial fluid, which helps to provide extra cushioning against impact.

Answer:

size of that species’ population.

Explanation:

The increase in the reproductive success of a species will have the greatest impact on the size of that species’ population.

A reproductive success rate means more individuals survive birth and get added to the existing population. The more the number of individuals added to a population, the more the size of the population of the species.

An increase in the population size of a species will only increase intra-species competition for resources but have no real impact on the success of other populations in the community.

b) an idea with lots of evidence to support it .

In science, the word theory refers to a comprehensive explanation of an important feature of nature that is supported by many facts gathered over time. Theories also allow scientists to make predictions about as yet unobserved phenomena.

Answer:

Potential targets:

1- DNA methyltransferases

2- Chromatin modifiers such as histone acetyltransferases, histone deacetylases, histone methyltransferases, etc.

3- Components of the RNA interference (RNAi) machinery such as Dicer, Argonaute, etc.

Explanation:

Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.

Answer:

Im pretty sure its B

Explanation:

Ecology.

The definition of ecology is: the branch of biology that deals with the relations of organisms to one another and to their physical surroundings.

This means that it is the study of how organisms interact with each other and their environment.

Not sure if it's right? Let's take a look at the other answers.

Definition of biosphere: the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms.

Definition of biotic: relating to or resulting from living things, especially in their ecological relations.

Definition of biome: a large naturally occurring community of flora and fauna occupying a major habitat, e.g. forest or tundra.

Answer:

Viruses are not living organisms, and for that reason a bacteriophage virus does not feed on bacteria, but uses them to replicate, producing lysis of the bacterial cell in the process.

Explanation:

Viruses are structures formed by genetic material —DNA or RNA—covered by a protein envelope called the viral capsid. These structures do not perform the vital functions of a cell, so they are not considered living organisms.

A bacteriophage virus is characterized by using prokaryotic cells to replicate, destroying them in the process.

Viruses need a living cell to be able to replicate, so they introduce their viral genome into them to replace the genetic material of their nucleus and be able to multiply. They can do this:

Bacteriophage viruses do not eat the bacteria, they simply use it to reproduce, and then happens the lysis of the bacterial cell.

WHAT IS THE MAJOR EVOLUTIONARY ADVANTAGE TO PRODUCING AN AMNION?

The main evolutionary advantage of producing an amnion is that the embryos of the amniotic membrane,the amniotes are made available with their own aquatic environment,this in-turn resulted to a lesser dependence on water for it's maturation and development therefore allowing or giving room for the amniotes to branch towards environments that are drier.

WHAT FOES THAT MEAN GOR EMBRYONIC DEVELOPMENT OF THE ANIMAL PHYLUM AS COMPARED TO THE ANIMAL PHYLA?

The embryonic development of animal phylum is also known as embryogenesis.

It is the development of the embryo from the point of fertilization of an egg,(the ovum) by a sperm cell ,this makes the fertilized egg a diploid cell otherwise known as a zygote.

This zygote undergoes mitosis,a mitotic division known as cleavage and a differentiation resulting in a multicellular embryo.

This embryonic development of animal phylum comprises of 36 animal phyla.

Explanation:

Lactose tolerance is basically an adaptation of the body in those humans who continue to drink milk throughout their lives, once the growth stage is over, milk should be suspended, although some continue to consume it and lactase continues to be encoded and expressed.

Some people for cultural reasons or environmentalist lifestyles do not drink animal milk, but rather vegetable milk.

Answer:

its human activity that change ecosystems

Ecosystem survival during earth change is helped by biodiversity, which produces a quality environment, hence option b is correct.

Ecosystem drivers encompass both natural and human-made elements. For example, habitat change and over-exploitation are direct causes that overtly affect ecological processes.

The effects of human activities on land and in the sea may have a significant impact on ecosystems. Among the various issues that ecosystems face include climate change and ocean acidification.

Biodiversity produces a quality of the environment that combine with oxygen, clean air, and water, pollinates plants, controls pests, treats sewage, and provides a wide range of other ecosystem services.

Therefore biodiversity provides an environment for the ecosystem when the earth changes, hence option b is correct.

Answer:INTERSPECIFIC COMPETITION

Explanation:

The physical factor that determines the number of organisms in a population is ;   Interspecific competition

Interspecific competition in a population is a competition that exists between organisms of different species, while the competition that occurs within organisms of the same specie is termed intraspecific competition.

During Interspecific competition the different species compete for food, water and Habitat which every organism needs to survive, and in most cases the stronger specie overruns the weaker species and this will lead to the depletion in the number of the organisms of the weaker specie and an increase in the number of the stronger specie within the population.

Hence we can conclude that The physical factor that determines the number of organisms in a population is ; Interspecific competition .

Plants get their nitrogen indirectly from the air via microorganisms in the soil and in certain plant roots.

Answer:

Microorganisms and certain plant roots in the soil

Explanation:

"Plants get the nitrogen that they need from the soil, where it's already been fixed by bacteria and archaea. Bacteria and archaea in the soil and in the roots of some plants have the ability to convert molecular nitrogen from the air (N2) to ammonia (NH3)... Such organisms are called "diazotrophs". From here, various microorganisms convert ammonia to other nitrogen compounds that are easier for plants to use. In this way, plants get their nitrogen indirectly from the air via microorganisms in the soil and in certain plant roots."
