Explanation:

Answer:

Each apron costs $ 12.75, and to make a profit of $ 1.75 they should be sold for $ 14.50.

Explanation:

Since the fifth grade craft club is making aprons to sell, and each apron take 1.25 yards of fabric that costs $ 3 per yard and 4.5 yards of trim that costs $ 2 per yard, to determine what does it cost the club to make one apron, and, if the club wants to make $ 1.75 profit on each apron, how much should they charge per apron, the following calculations must be performed:

1 apron = 1.25 yards of fabric at $ 3 per yard and 4.5 yards of trim at $ 2 per yard

1.25 x 3 + 4.5 x 2 = X

3.75 + 9 = X

12.75 = X

12.75 + 1.75 = 14.50

Therefore, each apron costs $ 12.75, and to make a profit of $ 1.75 they should be sold for $ 14.50.

Answer:

True

Explanation:

As the intensity of stimulus increases abruptly then response increase in continuous as different absolute intensities. In fact the brain is able to respond to the differential change in magnitude of stimuli and not the absolute change in magnitude.

Hence, the given statement is true

The sentence that uses the supporting evidence to form the best conclusion about a rattlesnake is as follows:

The rattlesnake's body temperature responded quickly to the environment, so it is an ectotherm.

Thus, the correct option for this question is C.

What are Ectotherms?

Ectotherms may be defined as the type of organisms that can not able to maintain their internal body temperature. They are also known as Poikilotherms. These types of organisms are absent on poles.

Due to a lack of internal maintenance of temperature, they can undergo hibernation and aestivation. Snakes and reptiles are ectothermic in nature. This significantly means that they directly obtain body heat from their environment.

Therefore, the rattlesnake's body temperature responded quickly to the environment, so it is an ectotherm is a sentence that uses the supporting evidence to form the best conclusion about a rattlesnake. Thus, the correct option for this question is C.

Answer:

They can cause the deprivation of nutrients, fluids, and metabolites. this may also cause pathological effects in their hosts such as pathogenic effects.

Answer:

A. Charles Darwin.

B. hom*ologous structure

C. Adaptation.

D. Speciation.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.

A. Charles Darwin: he developed the theory of natural selection based on certain evidences. Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

B. hom*ologous structure: it involves similar anatomical structures that are having common ancestry or from the same lineage.

C. Adaptation: it is an inherited trait that allows individuals to survive better.

D. Speciation: it is an ecological and biological process through which new species are formed due to isolation.

Explanation:

Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

1. The correct answer would be C) respiratory system.

Respiratory system is made up of set of organs which help in taking in oxygen and expelling out carbon dioxide from the body.

In humans, it is composed of nose, pharynx, larynx, trachea, bronchi, pair of lungs, and diaphragm.

Alveoli (in lungs) are the site of gaseous exchange where oxygen is exchange with carbon dioxide.

Carbon dioxide is the toxic waste product of cellular respiration. Circulatory system helps in transporting CO₂ from cells to the alveolar site where it is exchanged with oxygen and excreted out as a part of exhaled air.

Dead cells are shed at a more rapid rate is evidence that cells no longer respond to external factors and may have turned cancerous.

What are the cancer cells?

Cancer cells are defined as cells which divide continually, forming solid tumors or flooding the blood with abnormal cells. Cell division is a normal process used by the body for growth and repair.

Sometimes this orderly process breaks down, and abnormal or damaged cells grow and multiply when they shouldn’t. These cells may form tumors, which are lumps of tissue.

Answer:

1.) Surface area

2.) Digestive system

3.) Respiratory system

4.) Urinary system

5.) Circulatory system

6.) Interstitial fluid

Explanation:

In higher complex animals, such as the vertebrates, the internal exchange surfaces are modified in such a way to facilitate the transfer of materials from cell to cell in the body. As animal size increases, diffusion distances increase and the ratio of surface area to volume drops. Larger organisms have had to evolve specialized systems that are made up of structures that provides a large surface area for internal exchange of materials. Examples of these systems include:

--> DIGESTIVE SYSTEM: The fingerlike projections of the lining of the intestine provide a large surface area for the absorption of nutrients.

--> RESPIRATORY SYSTEM: This ends with a sac called the alveolar sac. The anatomical arrangement of capillaries and alveoli produces a very large surface area that is available for gas exchange.

--> URINARY SYSTEM: wastes are easily removed from the blood across the epithelial linings of excretory tubes.

--> CIRCULATORY SYSTEM: transports materials between the exchange surfaces of other organ systems and body cells. An example is seen in the relationship between the alveoli and the capillaries surrounding it.

For any exchange of materials to occur between cells the fluid known as the INTERSTITIAL FLUID which fills the intercellular spaces allows dissolved materials to be exchanged between body cells and the blood

Uncontrolled cell division is a cellular mechanism which causes cancer, hence option B is correct.

What is cancer?

A phrase for conditions where aberrant cells can infect surrounding tissues and divide uncontrollably. The lymphatic and vascular systems of the body are further routes by which cancer cells might spread.

Cancer is a condition wherein a few of the body's cells grow out of control. Cancer comes in many forms, and each one starts when a single cell experiences a genetic change (or mutation) that enables the cell to divide and multiply uncontrollably.

When one or more genes change and produce malignant cells, cancer begins. Tumors are formed by these cancerous cell groupings.

Therefore, cancerous cells may separate from tumors and spread to other parts of your body through your lymphatic system or circulation.

The pros of GMO crops are that they may contain more nutrients, are grown with fewer pesticides, and are usually cheaper than their non-GMO counterparts. The cons of GMO foods are that they may cause allergic reactions because of their altered DNA and they may increase antibiotic resistance.

Today, those who directly see the most benefits from GMOs are farmers and agricultural companies. ... GMOs are also used to produce many medicines and vaccines that help treat or prevent diseases. Before GMOs, many common medicines had to be extracted from blood donors, animal parts, or even cadavers.

There are multiple positive aspects of GMO, but it has many drawbacks as well. Genetically modified foods can become more resistant to disease, pests, and even natural disasters(floods, drought, etc.)
