The correct answer is "Hyphae".

In most organisms who have hyphae, the hyphae are the main way of vegetative growth and are collectively called the mycelium. They also occur in yeasts and fungi.

Answer: The correct answer is -

Hyphae.

Mold can be described as a fungus, which primarily grows in multicellular filaments that is threadlike form, called hyphae.

In most of the fungi, hyphae are considered as the main mode of vegetative growth, and together they are termed as mycelium.

Thus, Hyphae is the right answer.

g100num [7]

Answer: C) 13.5

Explanation:

Given that the frequency of an allele in a manatee population is 0.15 and said population is at Hard-Weinberg (a well-known equation usually used to calculating processes regarding allele and genotype frequencies), the correct number of 600 individuals that should be homozygous for the allele is <u>13.5 individuals.</u>

Dafna11 [192]

Answer:

Plant-eating animals are called PRIMARY CONSUMERS.

Explanation:

In an ecosystem, consumers are heterotrophic organisms that can not make their own food. They rather depend on producers or other consumers for food and nutrition. The organisms that derive their nutrition directly from plants are called primary consumers. They are also called herbivores as they feed on plant and plant products. For example, deer graze grasses. This makes deer a primary consumer and a herbivore.

Five ways that the membrane can deal with material

alexgriva [62]

Explanation:

Membranes function in a variety of ways. They maintain the osmotic balance (solute concentrations) within cells, keep foreign substances and other cells out, and expel waste...

This is further broken down as:

passive diffusion - some small ions may cross the membrane at will, anytime without restrictions
active transport - moves molecules across the membrane against their concentration gradient
facilitated diffusion - only allows specific substances to cross the membrane via transport proteins after they are recognised
exocytosis- expulsion of waste material from the cell
highly charged, and otherwise large molecules are prevented from crossing the membrane- these require specialized mechanisms like endocytosis

Active transport is a mediated process that requires an energy input and the use of specialized membrane proteins to move against the concentration gradient. These proteins require energy in the form of adenosine triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules to alter the spatial location of the molecule. For instance, with Na+, K+ pumps in cell membranes.

However, via passive transport or diffusion, small molecules can move from regions of high concentration to regions of low concentration until an equilibrium is reached. This occurs along the concentration gradient, and usually involves small non polar molecules in cells such as oxygen and carbon dioxide.

Facilitated diffusion is used for the transport of large molecules unable to cross the plasma membrane at will. However, passive diffusion, describes the movement of substances (small molecules and ions) across the membrane, along their concentration gradient.

During endocytosis large molecules cells and cell fragments moved across the plasma membrane through a process of invagination; piece of the external cell membrane falls into itself and forms a small pocket that surrounds the target molecule, this breaks off from the membrane to form an intracellular vesicle.

In exocytosis, large particles (proteins, neurotransmitters, waste material etc.) are surrounded by a phospholipid membrane in a vesicle. However, this membrane is formed in the cytoplasm, and attaches to the plasma membrane’s interior in a process opposite to endocytosis; material is removed from the cell and exported into the cell’s exterior called the extracellular space.
