Answer:

A) A tentative statement used to guide a scientific investigation is called scientific hypothesis.

As hypothesis is a proposed details of a phenomena, it can guide us in one way or another to carry out the scientific investigation.

B) Makes prediction about future events is scientific hypothesis.

Scientific hypothesis bases on the observation made predicts about future events, which could be either true or false.

C) Can be tested many independent researches is a scientific theory.

A scientific theory is developed when it has been passed through many researches and had gained acceptance too.

D) Both Scientific theory and hypothesis are based on the observations of the natural phenomena.

Firstly, an observation is made based on natural phenomena, which leads to questions, then research or study is carried out to answer these questions leading to the formation of a hypothesis which upon successful testing forms a theory.

E) Scientific theory is a well-established highly reliable explanation.

It a highly sustained explanation based on facts of nature, that are confirmed via a lot of experiments.

What is the phenotype of a plant with the genotype RR

vazorg [7]

To give a direct answer, I’d have to know what gene we were looking at. However, in a general sense, when a genotype has two capital letters, it means that it’s homozygous dominant. Take for example:

R= tall stalk
r= short stalk

The uppercase R is a dominant allele, which means if the plant has the gene with this in it (RR or Rr) then it will have that trait. If it has two lowercase letters (rr) then it will be the recessive trait.

Using this example, RR would be the tall stalk. For whatever your question is, the dominant phenotype would be the answer.

A pregnant woman found a large variety of microbes that can be vertically transmitted. She is making a list for her doctor to as

natta225 [31]

Answer:

Hyphae: Cell filaments,mostly septate

Mycelium: Mass of hyphae

Molds: mostly filamentous, Yeasts: non-filamentous,unicellular fungi

Budding yeasts divide asymmetrically.

Dimorphic fungi: yeast-like at 37°C, mold-like at 25°C.

Fungal spores are reproductive spores (unlike bacterial spores). Used to differentiate fungi.

Growth in acidic, low-moisture, high osmotic pressure environments.

The thallus (body) of a mold or fleshy fungus consists of long filaments of cells joined together; these filaments are called hyphae. Hyphae can grow to immense proportions. The hyphae of a single fungus in Oregon extend across 3.5 miles.

In most molds, the hyphae contain cross-walls called septa (singular: septum), which divide them into distinct, uninucleate (one-nucleus) cell-like units. These hyphae are called septate hyphae. In a few classes of fungi, the hyphae contain no septa and appear as long, continuous cells with many nuclei. These are called coenocytic hyphae. Even in fungi with septate hyphae, there are usually openings in the septa that make the cytoplasm of adjacent "cells" continuous; these fungi are actually coenocytic organisms, too.

Mycelium a mass of long filaments of cells that bring and intertwine, typically found in molds.

What can be said about the diversity of life in the high tide zone compared to that of the low tide zone?

Airida [17]

Answer:

B. There is less biodiversity in the high tide zone because the tidal changes make survival difficult.

Explanation:

The high tide and low tide zones are located on the seashore as the ocean water merges with land.

High tide zones are usually covered with water during high ocean tide while low tide zones are always submerged in water.

There is low biodiversity in the high tide zone because the tide here changes rapidly and organisms find it difficult to adapt. Organisms that inhabit here must be welll adapted to withstand peroids of high tides.

Why pancreas is called both exocrine and endocrine gland?

PolarNik [594]

Answer:

This question is in my stored notes read below

Explanation:

Pancreas is an exocrine gland as it has a duct to store pancreatic juice secreted by the pancreas and use it whenever required. It is considered as a endocrine gland as it does not have a duct to store the hormones insulin and glucagon which are directly supplied to the blood stream.
