Cells are the primary unit of structure in living organisms.

=============================================================

Explanation:

According to cell theory, cells are the building blocks of any living organism. This pertains to unicellular organisms (aka creatures that are one cell only) or multicellular organisms. This is why choice D is the answer.

Choice A is false because animal cells range in size. The largest animal cell is the ostrich egg that is about 5.1 inches across. In contrast, a neuron in the human body is about 100 microns across.

Choice B is false because plant cells have different shapes depending on the role they play in the plant itself.

Choice C is false. The number of cells varies even within the same species of a plant or animal. This is because the number is randomly determined and changes all the time. Old cells die and new ones are created constantly.

Answer:

Convergent boundary.

Explanation:

A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.

Explanation:

Monoculture is an agricultural practice that often decreases biodiversity.  Therefore, option (B) is correct.

Monoculture is the practice of planting only one type of crop on a large scale, which can lead to a reduction in the diversity of plant and animal species in the area. When a single crop is planted over a large area, it can disrupt the natural ecological balance of the region, leading to a decline in the number and variety of species that can survive in the area.

In contrast, tiling soil, synthetic fertilizers, and flood irrigation do not necessarily decrease biodiversity on their own. However, the use of these practices may have negative impacts on the environment, such as soil degradation and contamination of water resources, which can indirectly affect biodiversity.

Answer:

Materials can be classified according to the amount and type of light they transmit. Transparent (trans-PAIR-uhnt) materials allow most of the light that strikes them to pass through. It is possible to see objects through a transparent material. Air, water, and clear glass are trans- parent.

Glucose provides plants with needed food through a process called photosynthesis. This process helps plants convert the energy they take in from sunlight into sugar to help nourish the plant. Photosynthesis occurs when carbon dioxide, water and sunlight are combined. Plants use these to form glucose and oxygen.

Answer:

ATP and NADPH

There are two end products of the light reaction of photosynthesis, ATP and NADPH. These molecules are produced during the cyclic and the non-cyclic photophosphorylation reactions. These are the products which are used in the dark reactions.

Explanation:

Answer: Its A

Explanation: You're welcome

Increased daylight hours and temperature. Therefore,  option (A) is correct.

Florida flora respond to spring lighting and temperature. Photosynthesis requires sunlight, which increases as days lengthen. Plants develop and metabolically activate due to prolonged sunshine exposure.

Additionally, spring temperatures boost plant growth. Enzymes, nutrient absorption, and cellular mechanisms increase photosynthesis and plant growth at warmer temperatures.

Florida plants start growing when daylight and temperature increase. It grows new roots, leaves, buds, and flowers. These reactions increase energy capture, nutrient absorption, and reproduction, maximising plant output and adding to Florida's ecosystems' vitality and diversity. Therefore,  option (A) is correct.

The percentage of the food waste were lost in dairy items is 35%. The correct option is A.

Dairy products include staples from Western grocery stores including yoghurt, cheese, and butter.

Milk and any dish manufactured from milk, such as butter, cheese, ice cream, yoghurt, condensed and dried milk, are both considered dairy products.

The product losses = 17 - (4 + 2 + 5) = 6

So, the percentage = 6/17= ~35%

Thus, the correct option is A.

If 'Two brown-eyed parents have a child and has blue eyes, then the term that best describes the allele for the child's blue eyes is recessive (option d).

A recessive gene allele variant is any trait that is masked in heterozygous individuals due to the lack of expression of the allele, which is only expressed in homozygous individuals that has two copies of the same recessive alle (it can't be masked by the dominant allele in these individuals because we don't have this allele).

Therefore, with this data, we can see that a recessive allele variant is any gene variant capable of expressing one in homozygous individuals because it is masked by the dominant allele in heterozygous individuals who express the dominant allele.
