Answer:

Pasteur observed that the broth in the straight-neck flask was discolored and cloudy, while the broth in the curved-neck flask had not changed.

Explanation:

He concluded that germs in the air were able to fall unobstructed down the straight-necked flask and contaminate the broth. The other flask, however, trapped germs in its curved neck,­ preventing them from reaching the broth, which never changed color or became cloudy.

Hope this helps.

Answer:

It is a seeded vascular plant.

It does not depend on insect pollination.

Explanation:

The complete question is: A scientist has discovered a new plant species in the Amazon rainforest. She tells her fellow scientists that the plant she has found produces a cone. What might they say about how this plant is different from an angiosperm? Its seeds have one or two cotyledons. Its stems' vascular bundles are scattered. It does not depend on insect pollination. It is a seeded vascular plant.

The correct option would be that the plant is a seeded vascular plant and does not depend on insect pollination.

Gymnosperms are the only group of plants that produce cones. They are one of the plant groups that have vascular tissues in the form of xylem and phloem as well as been able to produce seed in the form fo cones. Hence, they are said to be seeded vascular plants.

Gymnosperms also carry out their pollination by relying solely on wind for the transfer of their pollen grain to the female organ. In other words, they do not depend on insect for pollination.

Answer:No her diet does not. She is currently eating 128.52 calories each for protein, 289.17 calories from fat, and 1413.44 calories from carbs. This means she is consuming 6.6% of her diet from protein, 14.9%, of her diet from fat, and 73.2% of her diet from carbs.

The difference between a stable isotope and an unstable isotope

A "stable isotope" is any of two or more forms of an element whos nuclei contains the same number of protons and electrons, but a different number of neutrons. Stable isotopes remain unchanged indefinitely, but "unstable" (radioactive) isotopes undergo spontaneous disintegration.

Answer: It's different because it is a bacteria eater.

Explanation: A bacteriophage is a type of virus that infects bacteria. In fact, the word "bacteriophage" literally means "bacteria eater," because bacteriophages destroy their host cells. All bacteriophages are composed of a nucleic acid molecule that is surrounded by a protein structure.

Answer:

Even bacteria can get a virus! The viruses that infect bacteria are called bacteriophages.

Explanation:

A bacteriophage is a virus that infects bacteria.

A bacteriophage, or phage for short, is a virus that infects bacteria. Like other types of viruses, bacteriophages vary a lot in their shape and genetic material.

Answer:

Apron, gloves, closed toe shoes, goggles. Kim should also tie long hair back if she has it and should roll long sleeves up.

Explanation:

Immunoglobulin, is a large, Y-shaped protein produced mainly by plasma cells that is used by the immune system to neutralize pathogens such as pathogenic bacteria and viruses.

a gamete produced in meiosis is the correct answer .

Meiosis is the process  where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.

Humans have 46 chromosomes in every cell,  where 23 chromosomes t came from one of our parents and 23 very similar chromosomes that came from the other parents.

Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibres appear.

Secondly Prometaphase I where Spindle fibres attach to the  centromere followed by Metaphase I where The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.

Telophase I where Spindle fibres disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells.

Answer:

The theory of spontaneous generation suggested that the living organisms can come from inanimate objects, however, it is an obsolete theory that is disproved by many experiments. The very first experiment that disapproved it was the experiment by Francesco Redi in 1668.

He demonstrated that maggots come from the eggs of flies instead of rotting meat. He placed raw meat inside of every jar. Half the jars he left open and the other half, he covered with mesh. In open jars, he found maggots after some time but covered jars have no maggots. That proved that the maggots come from eggs of flies rather than rotten meat.

The presence of flies on the meat is responsible for the production of maggots in meat.

This experiment disproves the theory of spontaneous generation because maggots are produced from the flies not the rotten meat. According to spontaneous generation, living organisms are formed or develop from nonliving matter.

So by performing this experiment we can see that maggots are formed when the flies feed on the rotten meat otherwise no maggots are present if the flies are not present there so that's why we can conclude that this experiment rejects the theory of spontaneous generation.

Answer:

1. Option c

2. Option a

Explanation:

1. If there are 50 dominant alleles, this represent the frequency of dominant alleles p = 50/100 = 0.5

Using the formula p+q = 1 we can solve for the frequency of the recessive alleles q = 1 -0.5 = 0.5 = 50%.

2. the frequency of the recessive allele for a gene is 0.3 which is q = 0.3

From the Formula p + q = 1 we can solve for p the frequency of the dominant alleles = 1 - 0.3 = 0.7

To calculate for the number of heterozygotes, we use 2pq = 2 x 0.7 x 0.3 = 0.42

Answer:

a video that shows penguin species that have different mating dances

Explanation:

The question is incomplete as it does not have the options which are:

Answer:

a video that shows penguin species that have different mating dances

The reproductive isolation is the factor which allows the species to evolve and form a new species, therefore, this factor is used to describe a species.

The reproductive isolation refers to a mechanism in which the species are isolated to not interbreed with the individual of other species. The reproductive isolation could be due to behavioural, psychological, physical or genetic differences. evolved as an adaptation.

In the given cases, the penguin species which shows different mating dances is considered to be reproductively isolated as the different dance rituals evolved as behaviour to prevent them from mating.

Thus, the selected option is correct.

A video that shows a large river that has penguin populations on both sides would make the best project. So, the correct option is A.

A population is defined as the complete set of individuals, whether that group includes a nation or a group of people with a common characteristic which is the pool of individuals from which a statistical sample is drawn for a study. .

It is described as a unit of biological community made up of a permanent group of an interbreeding individual of a species found in a space or geographic region at a particular time. Population are of three types of population pyramids created from age-sex distributions-- expansive, constrictive and stationary.

Thus, a video that shows a large river that has penguin populations on both sides would make the best project. So, the correct option is A.
