Answer:

B. Begin dividing and growing larger.

Explanation:

When the sperm and egg cells fuse during fertilization they form a zygote. The zygote then starts to begin to divide rapidly and start growing larger and bigger.

After this process the cells then begin to become differentiated and the parts of the body now become more visible and pronounced.

Answer:

The correct answer is B. ribosomes.

Explanation:

Prokaryotic cells, like bacteria, are cells that do not have any organelles.  Unlike eukaryotic cells, they do not have a nucleus or other membrane-bound structures inside their cell membrane.  Therefore, prokaryotic cells do not have chloroplasts, mitochondria, or nuclei, but they do have ribosomes (as do eukaryotic cells) which are an important component of protein production in the cell.

Explanation:

The given case could progress into all the outcomes except intraspecific competition

Intraspecific interaction is a kind of interaction seen within the same species that compete for basic necessities for survival such as food, habitat, and water. It does not lead to evolutionary changes within the species, therefore they do not develop adaptations in response to the competition

Thus, it can be concluded that the adaptation in direct response to one another could lead to all except intraspecific interaction

The given question is incomplete as the group of choices lack the correct answer, however, the correct group of choices are as follows:

A. Movement of sister chromatids to opposite poles at anaphase II of meiosis.

B. Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.

C. Crossing over between homologous chromosomes during prophase I of meiosis.

D.  Replication of chromosomes prior to meiosis.

E. Independent alignment of different homologous pairs on the metaphase I spindle.

Answer:

The correct answer is :  Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.

Explanation:

The Mendel's law of segregation says that during formation of gametes the copies of genes segregate from each other so each gamete has equal and only one allele of the gene.

This behavior of homologous chromosome can be seen in anaphase I in meiosis, responsible for the segregation of copies of allele into different copies.

Thus, the correct answer is :  Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.

Answer:

B= inorganic

Explanation:

inorganic means not organic

Inorganic means that has never been living, the correct option is B.

Organic and inorganic compounds are the building blocks of chemistry. The main distinction among both organic and inorganic compounds is that organic compounds every time contain carbon, whereas most inorganic compounds do not.

Furthermore, almost all organic compounds encompass carbon-hydrogen or C-H bonds.

In other statements, inorganic refers to not being made up of or derived from living matter.

A living organism is made up of cells. The cells differentiate, and the organisms' bodies grow as the number of cells increases. A tree is a living organism that exhibits the growth process.

Thus, the correct option is B, as inorganic implies to the one that is not living.

Explanation:

When the environment becomes too hostile to aid the search for food (that is, dry season), the honeypot ant which can be referred to as repletes shows adaptation to its environment with the intelligent ability to store liquid food inside its abdomen.  Their expandable abdomen serve as “living larders” for their entire colony because they are storage vessels.

It exemplifies unity because during a dry season, nutrients become more scarce. Very few flowers blossoms, and fewer insects will approach the colony which means less access to food. Honeypot ants turn to their living larders, which would have swollen to the size of grapes.

When the colony is in need of nutrient-rich liquids, a worker ant will stroke a replete’s antennae. This signals the replete to regurgitate the liquid. A worker can eat the liquid itself, or carry it to another member of the colony.

It exemplifies diversity because it is different from other ants in its ability to store liquid food in its expandable abdomen. Many insects store sweet liquid for later use. For example, honeybees usually stores liquid in their combs. Honeypot ants, are the only insects to store the liquid in their own bodies.

Honey pot ants or honey ants are the types of worker ants. It exhibits adaptation to the surrounding by storing the food in its abdomen region and shows unity and diversity.

Honeypot ants belong to the genus Myrmecocystus is an arthropod and stores food like honey in the abdomen to the point of swelling and are 3 - 5 mm long.

They show adaptation when the environment becomes hostile and the food becomes scarce. They store the liquid food content in their abdomen and this swelled stored food of the abdomen acts as the living larders for the other ants of the colony.

Honeypot ant exemplifies the unity as during scarcity of food in off-seasons then the ants use their stored food or the larder to nourish the other ants of the colonies.

They are the tomb of the diversity as different from the other ants they store food in their own body rather some places of living like honey bees stores honey in the hives.

Therefore, honeypot ants show adaptation, unity and diversity.

Answer:

No, not really science has been proven wrong many times.

Explanation:

Answer and Explanation:

1. Hypothesis: The more sunflower seeds the students get, the better they will do on a quiz.

2. Dependent Variable: Responding variable refers to the dependant variable, which response depends on any change in the independent variable. A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. In the exposed example, the dependent variable is the response of each group to sunflowers seeds expressed as their grades on quizzes.

3. Independent Variable: number of sunflower seeds. Manipulated variable refers to all the variables in an experiment that provoke a response in another variable. They are also known as independent variables. The researcher can change these variables to see what changes it implies in an object, process, trait, or anything that depends on them. In the exposed example, the researcher manipulates the number of sunflower seeds promised to each group.

4. Constant Control Group: Group 1, which does not receive any sunflower seeds. The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study, in this case, the provision of sunflower seeds, from the results that might be a consequence of other factors. The control group must be selected from the same population of the treatment group. All groups must be similar in every variable that might influence the results, except for the study treatment

5. Experimental Group: Groups 2 and 3, that received different amounts of seeds.

Answer:

not all living things move

Explanation:

Animals which are living things have the ability to move as well as microrganisms however, plants and certain microrganisms do not have these abilities and yet are still living.

Answer:

Technically, all living things move in some way.

Different animals, like humans, dogs, and goats, can walk and run. Marine animals can swim and dive. Birds and some insects can fly around.

Plants can move, just not the same way animals can. For example, a sunflower will turn to face towards the sun. Although, plants don't have the ability to move from one place to another, or locomotion.

So, movement can be considered a characteristic of life, but locomotion is not. Plants and other living organisms cannot get up and move from one spot to another spot.
