Answer 1

Answer:

12) When a solid dissolves the solid (solute) and the liquid (solvent) form a very close intimate mixture called a solution

16) In other words, plasma membranes are selectively permeable—they allow some substances through but not others. ... The most direct forms of membrane transport are passive. Passive transport is a naturally occurring phenomenon and does not require the cell to expend energy to accomplish the movement.

19) To move substances against a concentration or electrochemical gradient, the cell must utilize energy in the form of ATP during active transport. Primary active transport, which is directly dependent on ATP, moves ions across a membrane and creates a difference in charge across that membrane.

what is a zygote? (5 sentences)

Answers

Zygote is a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum. A zygote is the union of the sperm cell and the egg cell. Also known as a fertilized ovum, the zygote begins as a single cell but divides rapidly in the days following fertilization. After this two-week period of cell division, the zygote eventually becomes an embryo. If it goes well, the embryo becomes a fetus.

A

Please mark brainliest if correct. Have a blessed day. :)

One of the unique properties of water is that it has the capacity to dissolve many substances. The correct option, in this case, would be A.

Water is often referred to as a universal solvent. This is because the liquid has the capacity to dissolve more substances than any other liquid known to exist in nature.

The ability of water to dissolve a wide range of substances has been linked to its chemical and physical properties, especially its polar nature. Water molecules are polar with slightly positive and negative charges, Thus, they are able to attract other types of molecules

The temperature deciduos forest and temperature grassland biomes have the same maximum temperature. Witch of the following is a reason they have different plant and animal species? A. They are at different altitudes B. They are at different latitudes C. The forest gets more precipitation D. The grassland gets more precipitation

Answers

Explanation:

Deciduous forest, vegetation composed primarily of broad-leaved trees that shed all their leaves during one season. Deciduous forest is found in three middle-latitude regions with a temperate climate characterized by a winter season and year-round precipitation: eastern North America, western Eurasia, and northeastern Asia. Deciduous forest also extends into more arid regions along stream banks and around bodies of water. For the deciduous forest of tropical regions, see monsoon forest.

Dorothe

Oaks, beeches, birches, chestnuts, aspens, elms, maples, and basswoods (or lindens) are the dominant trees in mid-latitude deciduous forests. They vary in shape and height and form dense growths that admit relatively little light through the leafy canopy. Shrubs are found primarily near clearings and forest edges, where more light is available, and herbaceous flowering plants are abundant within the forest in the spring, before the trees come into full leaf.

The soils upon which deciduous forests thrive are gray-brown and brown podzols. They are slightly acidic and have a granular humus layer known as mull, which is a porous mixture of organic material and mineral soil. Mull humus harbours many bacteria and invertebrate animals such as earthworms.

Snails, slugs, insects, and spiders are common inhabitants of the deciduous forest, and many cold-blooded vertebrates, such as snakes, frogs, salamanders, and turtles, are also present. Birds are represented by warblers, flycatchers, vireos, thrushes, woodpeckers, hawks, and owls. Prominent mammals include mice, moles, chipmunks, rabbits, weasels, foxes, bears, and deer.

A sample of DNA is collected from an organism. It is analyzed and determined that 20% of the DNA is made up of the base adenine. Based on this information, which of the following correctly lists the amounts of the three remaining bases for this sample

A 20% cytosine, 20% thymine, 20% guanine

B 30% cytosine, 209. thymine, 30% guanine

C 10% cytosine, 30% thymine. 40% guanine

D 30% cytosine, 30% thymine, 20% guanine​

Answers

Explanation:

According to the Chargaff's rules the DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of purine bases [for the DNA cytosine, thymine and for the RNA uracil] and pyrimidine bases [guanine and adenine for RNA and DNA]. The amount of guanine should be equaled to cytosine and the amount of adenine should be equaled to thymine. You can follow this rule in both strands of the DNA.

According to the information given above, the amount of the three remaining bases for this sample is 30% cytosine, 20% thymine, and 30% guanine. Thus, the correct option is B.

What are Bases?

Bases may be defined as the monomer of nucleic acids such as DNA or RNA. These nucleotide bases are composed of a pentose sugar, and a phosphate group.

There are four types of nucleotide bases that are generally found in any nucleic acid sequence. They are adenine, guanine, thymine, and cytosine. But in RNA, Thymine is replaced by Uracil.

According to Chargaff's rule, the amount of adenine is always equal to the amount of thymine, while the amount of guanine is always equal to the amount of cytosine.

A = T : G = C.

If the amount of adenine is 20%, the amount of thymine is also 20%. Together, they constitute 40% of DNA, now the remaining is 60%.

This 60% is then equally divided into two parts between 30% cytosine and 30% guanine.

Therefore, the amount of the three remaining bases for this sample is 30% cytosine, 20% thymine, and 30% guanine. Thus, the correct option is B.

What gives a plant cell structure?

Answers

Answer:

The cell was first discovered in 1665 by an English scientist named Robert Hooke. While looking through a microscope, he observed tiny box-like objects in a slice of cork (bark from an oak tree) and named these boxes cells. Cells are the basic units of life, which make up all living things. This idea forms the basis of the Cell Theory. Plant cells are larger because they contain all of these structures but have some unique structures like a cell wall, vacuole and chloroplasts.

All these specialised structures are called organelles. An organelle is a tiny structure inside an animal or plant cell that has a specific function or role.

Answer:

The cell wall provides strength and support to the plant, much like the exoskeleton of an insect or spider (our skeleton is on the inside of our body, rather than on the outside like insects or spiders).

The plant cell wall is mainly made up of the carbohydrates molecules cellulose and lignin. Cellulose is used extensively by humans for making paper. Cellulose can also be converted into cellulosic ethanol, a type of biofuel. Some animals, such as cows, sheep and goats, can digest cellulose with the help of bacteria in their stomachs. Humans cannot digest cellulose, which passes through our bodies and is better known as dietary fiber, something that we should eat to keep our waste moving as it should! Lignin fills in the spaces between cellulose and other molecules in the cell wall. Lignin also helps water molecules move from one side of the cell wall to the other – an important function in plants.

The introduction of which factor would least affect the biodiversity of an ecosystem?
A. A new disease
B. A native species
c. An invasive species
D. A human population

Answers

Answer:

Native species

Explanation:

New diseases could cause widespread illness and even death that could drastically affect trout population. Invasive species are unnatural towards an ecosystem because predators aren't adapted to hunt feral hogs. Human population causes habitat destruction and hunting of large megafauna like buffalo and elk.

Answer:

B. Native species.

Explanation:

Being a Native species (meaning the species belongs in that ecosystem), they would have almost no affect on the biodiversity of that ecosystem. Human population, invasive species (species that DO NOT belong in an ecosystem), or a new disease could be catastrophic to the biodiversity of an ecosystem.
