Answer:

The community will slowly decline, or be just fine, or be better off.

Explanation:

Wolves being killed in Yellowstone showed that Yellowstone suffered, because there was nothing to kill the elk, so their population exploded and they ate everything.

If certain rats were gone in certain areas, then the community/environment would be fine, because rats eat birds and other small animals (they eat too many of them).

And if stray cats were gone then certain forests would be better off and see an increase in birds population, stray cats eat birds.

Answer:In the rock cycle, rocks and matter go through uplift, weathering, erosion, deposition, melting, crystallization, and metamorphism as they travel between Earth's surface and its interior layers. In the water cycle, water particles undergo evaporation, condensation, precipitation, and flow.

Answer:

First law: In the ecosystem, the energy flow from lower levels of the food chain to the highest levels

Second law: During energy transference between trophic levels, the main part of the energy is lost as heat and other processes.

Explanation:

The first law of thermodynamics states that the energy can not be created or destroyed, but instead it is transformed into one type to another. Moreover, the second law states that when energy is transformed an important proportion of this energy is lost as heat, and it increases the entropy level.

In an ecosystem, the energy flow is unidirectional, it means that energy flow from primary producers to primary consumers, then from primary consumers to secondary consumers and so successively in all levels. Moreover, organisms fight against entropy by converting foods into energy (which is used to maintain order within their cells. During the feeding process, the energy intake is not 100 % efficient, it means that most part of the energy is lost as heat (approximately 90%), thereby increasing the entropy in the ecosystem.

Microscope where “micro” means small and scope is like a tool to see thing and salt crystals are small so be choice is microscope

A microscope is which produces large images of tiny  substance and provide observer a close view of minute structures at a convenient scale for examination and analysis.

Anatomically the microscope consist of  three structural parts, i.e. head, base, and arm, where head is known as the body and it carries the optical parts in the upper part of the microscope.

Base of microscope is used to support  and carries microscopic illuminators and Arms connect the base and the head and the eyepiece tube to the microscope base.

The optical parts are basically applied for the  view, magnify, and production of an image from a specimen placed and the various parts.

Eyepiece or ocular located at the top of the microscope with standard magnification is 10X, Eyepiece Tube which carries the eyepiece just above the objective lens.

Explanation:

Answer:

Daughters who are descendants of a woman carrier of Fragile X Syndrome and a healthy man will have a 50% chance of having or being carriers of the syndrome.

Explanation:

Fragile X syndrome has an autosomal dominant inheritance pattern, linked to the X chromosome. That is, someone with an altered X chromosome can either be a carrier or have the syndrome.

In this case, the mother is a carrier of the altered chromosome (X) while the father is neither a carrier nor has the condition (XY).

Cross X x XY

Alleles         X           Y

[tex]X^{f}[/tex]            [tex]X^{f}[/tex]X       [tex]X^{f}[/tex]Y

X               XX          XY

The couple has a 50% chance of having daughters, and of those daughters half (50%) have the chance of having an Xf chromosome, and being a carrier or suffering from the syndrome.

Answer:

The answer will be listed below.

Explanation:

1.)-

a.) G1 Phase- Following cytokinesis, during G1 phase the cells monitor environment for the potential growth factors, grow larger and once achieve the threshold size then starts the progression through S phase.

b.) S Phase- To produce two similar daughter cells, the complete DNA instructions in the cell must be duplicated. DNA replication occurs during this S phase.

c.) G2 Phase- During the gap between DNA synthesis and mitosis, the cell will continue to grow and produce new proteins. At the end of this gap is another control checkpoint to determine if the cell can now proceed to enter Mitosis and divide.

d.) Mitosis- Prophase, Metaphase, Anaphase, and Telophase occurs in Mitosis. During prophase, the parent cell chromosomes, which were duplicated during S phase, condense and become thousands of times more compact than they were during interphase.

Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. As metaphase continues, the cells partition into the two daughter cells.

Anaphase- In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell. The protein that holds the sister chromatids together is broken down, allowing them to separate.

During telophase (the final stage), the chromosomes arrive at the cell poles, the mitotic spindle disassembles, and the vesicles that contain fragments of the original nuclear membrane assemble around the two sets of chromosomes.

e.) Cytokinesis- During cytokinesis, the cytoplasm splits in two and the cell divides.

2.) They go through the process of Mitosis. Mitosis consists of four steps: Prophase, Metaphase, Anaphase, Telophase.

3.) Mitosis takes place all over the body, while meiosis only takes place in the sex organs and produces sex cells. Mitosis consists of one stage whereas meiosis consists of two stages. Mitosis produces diploid cells, whereas meiosis produces haploid cells. Mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.

A similarity between mitosis and meiosis is that they both produce new cells and start with one a single parent cell to duplicate.

4.) 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.

5.) The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment.

6.) A genotype refers to the genetic characteristics of an organism. A phenotype refers to the physical characteristics.

7.) The opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.

8.) Transcrption-

Initiation- The DNA molecule unwinds and separates to form a small open complex.

Elongation- RNA polymerase moves along the template strand, synthesising an mRNA molecule.

Termination- In prokaryotes there are two ways in which transcription is terminated.

Processing...

Translation- Translation happens in four stages: activation (make ready), initiation (start), elongation (make longer) and termination (stop). These terms describe the growth of the amino acid chain (polypeptide).

9.) A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses. Mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.

10.) DNA fingerprinting is a method used to identify an individual from a sample of DNA by looking at unique patterns in their DNA.

Answer:

Your genome is inherited from your parents, half from your mother and half from your father. The gametes are formed during a process called meiosis. Like your genome, each gamete is unique, which explains why siblings from the same parents do not look the same.

The need to be able to pass nutrients and gases into and out of the cell sets a limit on how big cells can be. The larger a cell gets, the more difficult it is for nutrients and gases to move in and out of the cell. As a cell grows, its volume increases more quickly than its surface area.

The control group is the main one because it acts as a benchmark to balance the results of the experiment.

Control groups are a principal aspect of true experimental designs. The presence of control groups authorizes researchers to confirm that study results are due to the drafts of independent variables rather than irrelevant variables. The control group of an experiment is a group that is not revealed to the independent variable and thus serves as a benchmark to which to compare the outcome of the experimental group. An experimental group, also known as a use of group, receives the treatment whose effect researchers wish to study, whereas a control group does not. They should be similar in all other ways.

So we can conclude that an example of a control group is a group of individuals in a detached trial that receive placebo pills instead of medication.

Answer:

When the concentration of molecules of a substance is the same on both sides of a membrane the solution is isotonic.

Explanation:

A given substance, when it has the same concentration on both sides of the membrane, is in equilibrium and the solution is called isotonic, from the extracellular space with respect to the cytoplasm.

The cell membrane is semipermeable to the passage of water and some substances. Hypertonic and hypotonic solutions tend to establish the dynamics of entry and exit of molecules or water, due to the concentration or osmotic gradients that are established, respectively.

An isotonic solution does not generate gradients, because the concentration of molecules is equal in the extracellular space with respect to the intracellular space.
