Answer:

Plant reproduction is the development of new offspring that can be achieved through sexual or asexual reproduction in plants. By the fusion of gametes, sexual reproduction creates embryos, resulting in offspring genetically distinct from the parent or parents. Asexual reproduction creates new individuals, genetically similar to the parent plants, without the fusion of gametes.

Explanation:

a. The 4-acre field will support a total of 200 g foxes at any given time.

b. The pyramid is attached.

a. To calculate the number of foxes that the field could support at any given time, we need to work our way up the food chain, starting with the mallow plants:

200 kg of mallow plants x 10% = 20 kg available to painted lady butterflies

20 kg of painted lady butterflies x 10% = 2 kg available to phoebes

2 kg of phoebes x 10% = 0.2 kg available to foxes

Now to convert kg to g to make the calculations easier:

200 kg = 200,000 g of mallow plants

0.1 g per painted lady butterfly x 20 kg of painted lady butterflies = 2000 g = 2 kg

48 g per phoebe x 2 kg of phoebes = 96,000 g = 96 kg

1000 g per fox x 0.2 kg of foxes = 200 g

Therefore, the 4-acre field could support approximately 200 g of foxes at any given time.

b. The biomass pyramid diagram is attached below.

To convert from kg per acre to g per square meter, multiply by a factor of 24.711 (since there are approximately 4046.86 square meters in an acre).

food safety is a risk based process is true

Answer:

The entrance of the antigen activates cell signaling pathways through cytokines secreted by B cells, thereby triggering an immune response >> Subsequently, B cells also act in antigen processing by presenting them to T-cells.

Explanation:

An antigen is a molecule that binds to an antibody or a B cell receptor. Cell interaction is produced by direct contact of cells in multicellular organisms and this interaction may also be associated with immune responses through intercellular communication by cytokines. The cytokines are released and then bind to cell receptors to trigger an immune response (for instance, inflammation). It is possible to trace the secretion of cytokines and their corresponding receptors by analyzing specific gene expression patterns. The B cells are critical components of the immune system because they release cytokines in response to antigenic stimuli, and they also present antigens to T cells.

Answer:

The water vapor content in the atmosphere is typically recorded using a measurement called relative humidity, which represents the amount of water vapor present in the air relative to the maximum amount the air could hold at a given temperature. Therefore, if two locations have different water vapor content in the atmosphere, it is likely that they would have different relative humidity readings.

For example, if one location has a higher water vapor content in the air, it would have a higher relative humidity measurement than a location with a lower water vapor content. Conversely, if one location has a lower water vapor content in the air, it would have a lower relative humidity measurement than a location with a higher water vapor content.

It is important to note that other factors can also influence relative humidity measurements, such as temperature and atmospheric pressure, so a direct comparison of relative humidity readings between two locations should take these factors into account.

Answer:

Red blood cells carry oxygen; white blood cells fight disease.

Explanation:

Confirmed, just did it.

Red blood cells carry oxygen; white blood cells fight disease. Therefore, option "B" is correct.

The blood cells are produced in the bone marrow of the bones and are present in the blood. A protein found in red blood cells that transports oxygen from the lungs to every cell in the body is hemoglobin.

The immune system of the body is constituted of white blood cells. They empower the body's defense against disease and infection. Granulocytes, monocytes, and lymphocytes (T and B cells) are examples of white blood cells.

Red platelets or RBCs convey oxygen to the tissues in various pieces of the body. By producing antibodies, white blood cells, or WBC, strengthen the body's defenses.  The complete blood test is used to detect disease.

The process represented by 1 and 2 could be meiosis which is a type of cell division. The process represented by 3 could be fertilization which is the fusion of gametes to form a zygote.

The process of cell division called meiosis, that produces gametes with half the number of chromosomes as the parent cell is responsible for producing gametes. The genetic information provided by a parent to its offspring is determined by heredity and varies from one individual to another as do other genetically determined traits.

The life cycle of humans is divided into different stages. The sperm from the adult male human and the egg from the adult female human form a zygote inside the uterus. This zygote then undergoes mitosis to form an embryo. The embryo then develops into a fetus which is born after around nine months.

When X fires 10 times and Y fires 10 times, the result will be a subthreshold summation.

Subthreshold summation happens when two or more presynaptic inputs that are sub-threshold (i.e., they cannot create an action potential) combine their effects on the postsynaptic neuron.

Here, the postsynaptic neuron has an RMP of -70mV and a typical threshold of -55mV. When neuron X is stimulated, it depolarizes by 0.5 mV.

When X and Y are stimulated simultaneously, the postsynaptic neuron depolarizes by 1 mV, which is sub-threshold (below -55mV).

Therefore, when X fires 10 times and Y fires 10 times, the postsynaptic neuron will experience subthreshold summation and no action potential will be fired.

The relationship between predation and herbivore weight shown in Figure 3 suggests that heavier herbivores experience lower predation rates. This may be due to their size providing a physical advantage or their ability to access more abundant food resources.

First, larger herbivores may be less vulnerable to predation because they are physically larger and stronger, which can make them more difficult to subdue and kill.

Second, larger herbivores may have longer lifespans and thus more time to develop anti-predator behaviors or to learn how to avoid predators.

Third, larger herbivores may be more efficient at processing vegetation and obtaining nutrients, which can lead to better physical condition and overall health, making them less susceptible to predation.

Fourth, larger herbivores may have larger social groups, which can provide protection against predators by allowing for coordinated defense and increased vigilance.

Finally, larger herbivores may inhabit areas with more abundant resources or better cover, reducing their exposure to predators.

Overall, the relationship between predation and herbivore weight shown in Figure 3 is likely a complex interplay of these and other factors that affect the vulnerability of herbivores to predation.

The sperm of an angiosperm reach the egg via the pollen tube that grows from the pollen grain through the carpel tissues to the ovule.

Hence, the correct answer is option B.

Pollen is a fine powder that seed plants produce. Pollen grains (extremely reduced microgametophytes), which create male gametes, make up this substance (sperm cells). In the process of moving from the stamens to the pistil of flowering plants or from the male cone to the female cone of gymnosperms, gametophytes in pollen grains are shielded by a tough coating comprised of sporopollenin.

When pollen touches a pistil or female cone that is compatible with it, it germinates and creates a pollen tube that carries the sperm to the ovule that houses the female gametophyte. Pollen grains are so tiny that they must be magnified to be seen in detail. Paleoecology, palaeontology, archaeology, and forensics all benefit greatly from the study of pollen, which is known as palynology.
