[7 pts] In threespine stickleback fish, independently assorting genes determine the extent of body armor (left) and pelvic spines (right): You cross two full-armored, full-spined parents and get these offspring: 79 full-full; 23 full-armored w/ reduced-spines. a) State one set of possible genotypes for the parents: Parent 1: __________; Parent 2: __________ b) What are the dimensions of the smallest Punnet square you can use to confirm your answer to Part (a)

Answer:

B. The law of conservation of mass has already been applied. There is an equal number of each element on both sides of the equation.

Explanation:

took the test

Answer:d. Covalent, ionic, hydrogen

Explanation:

Answer:

Covalent, ionic, hydrogen

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.

Explanation:

inter relation

living and non living

Answer:

Bare soil is exposed, weeds and grasses colonize, perennial plants are established, shrubs appear, trees appear, and forest results

Explanation:

This question describes a secondary succession, which is a colonization that occurs after a natural disaster has caused damage to an ecosystem. In secondary succession, SOIL, is already present, hence, there is rapid initial recolonization by GRASSES AND WEEDS.

The colonization of grasses and weeds is soon followed by the establishment of PERENNIAL PLANTS, after which SHRUBS appear, then TREES until a stable or climax ecosystem of FOREST results.

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 .

Answer:

D

Explanation:

Refraction is generally defined as the change in the direction of a wave as it travels from one medium to another. Light is a form of wave and light refraction is caused by a change in the speed of light as it moves from air to water, causing the light to bend in the process. The medium of travelling has to be transparent.

The change in the speed and direction is due to the variability in the refractive index of media. Light travels faster as it moves from a medium of higher refractive index to a medium of lower refractive index and vice versa.

The correct option is D.

Answer:

C

Explanation:

It has a round shape so obviously plant cell. You can see the vacuoles, mitochondria, and E.R., but it's missing its nucleus.

Answer:

D

Explanation:

A plant cell would have a cell wall to make the cell structured and more rectangular, so the other answer is incorrect. This is an animal cell. You can tell because there is no cell wall and the vacuoles are smaller (plant cells usually only have 1 large vacuole), and there are no chloroplasts. There is no nucleus pictured and since it is an animal cell, the cell doesn't need chloroplasts. That means that the answer is D.

Eclipses only occur during full and new moons. Earth rotates around its axis faster than the moon. ... The moon's axis does not always align with Earth's shadow.

Explanation:

Answer:

The moon's axis does not always align with Earth's shadow.

Explanation:

The Earth goes around the Sun, while the moon goes around the Earth, so all of them lining up exactly doesn't happen that much. I also jus got it right.

Answer: From the onlookers, the two are clearly far away. The two girls are Kelveys and the talker: "Many kids including Burnells do not even talk to them, they passed through Kelveys in the air ... Kelveys everyone ran away" (Mansfield 203) Negative feelings affect not only my own emotions, but for very young people there is the possibility that it will affect not only the other people but also how to handle themselves.

From her "pigeon's nest" and "other stories" series, the story is told by an unknown narrator of a third party, after reading the story, the reader will find that Mansfield is exploring the theme of the classroom I notice.

In addition to Kezia, the Burnell family thinks that himself is higher than others, especially in Kelveys. Burnells seems to define himself through his social position (or class), and Mrs. Kelvey is a working-class woman and Mr. Kelvey can happen in prison, Burnells himself as Kelveys I believe it is higher. There is also a sense that Burnel refuses Kelvey as they may be different from them.

Answer:

The bipedality

Explanation:

One of the things the discovered fossil signified was that human bipedality was more ancient than the large brain size because Lucy actually had a small skull which could indirectly be translated to small brain size.

NOTE: Bipedality can be described to mean the ability of an organism to move about with two legs. Hence, it must have been discovered that Lucy had two legs.

Answer:

The slow depolarization of the pacemaker cells is caused by the opening of the non selective cation channels.

Explanation:

Pacemaker cells are specialized cardiac muscle cells with the task to create the rhythmic pulses that make the cardiac muscle contract properly, functioning as a whole and not as independent contractile cells.

One of the things that differentiate pacemaker cells from regular cardiomyocytes is that pacemaker cells slowly depolarize by themselves. This happens because when these cells are in phase 4, in a state of hyperpolarization, the 'funny current' appears to begin depolarizing the cell again.

Hyperpolarization usually occurs because there's an outflux of potassium ions (which makes the inside of the cell much more negative than the outside of the cell) but, in pacemaker cells, the membrane becomes less and less permeable to potassium, which ends up decreasing the outflux of this ion. Along with this change in potassium's electrical conductance, the funny current increases the permeability of sodium, which means that there's also a sodium influx happening at the same time, helping in the depolarization process.

This mixed sodium and potassium permeability is one of the key features of the funny current, and is possible thanks to the opening of non-selective cation channels in the membrane that allow the passing of any cation following their specific chemical gradients.

because the mitochondria makes energy and the cell wall lets things in and out of it

Answer:

D

In animal cells, the cell membrane allows for materials in and out of the cell, while the mitchondria uses nutrients to make energy (ATP) for the cell

Explanation:

To figure out how to eliminate answers you need to know what the functions of the cell wall and the mitchondria are.

The mitochondria is referred to as the power house of the cell meaning that it creates energy for the cell.

The cell wall allows things in and out and is the protector of the cell.

Answer:

The name of the test which can increase the accuracy of the identification of the organism is Coagulase testing.

Explanation:

Given the points stated in the question, the organism most likely under scrutiny here is Staphylococcus Aureus. Science has shown that it is the most harmful of all of the many different staphylococcal bacteria that there is.

The best test for differentiating and identifying Staphylococcus Aureus apart from other types of other Gram-positive cocci is the coagulase test.

The coagulase test checks to see if the microbe can produce an exoenzyme called coagulase.

Coagulase - an exoenzyme, is usually produced by bacteria. This enzyme triggers the coagulation of blood or plasma.

Only the pathogenic or disease-causing forms of staphylococcus can produce this enzyme. The enzyme is qualified by the suffice  "exo" because the enzyme is secreted externally and not internally. Also, its functions are external, not internal.

The Coagulase testing is of two types:

It is usually safer to use the test tube method. If one must rely on the slide test, the results must be read quickly as it is prone to false positives.
