What is the structure of a virus?

Answers

Answer 1

Answer:

The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.

A virion consists of a nucleic acid core, an outer protein coating or capsid, and sometimes an outer envelope made of protein and phospholipid membranes derived from the host cell. The capsid is made up of protein subunits called capsomeres. Viruses may also contain additional proteins, such as enzymes

Hydrophobic interactions are the basis for Sudan tests. Explain how hydrocarbons in lipids interact with polar surroundings

Answers

Answer and Explanation:

Lipids are non-polar molecules, so they do not interact preferentially with polar molecules but they can interact with each other. In a polar medium, such as water, the hydrocarbons in lipids aggregate each other, in order to minimize contact with surrounding polar molecules. The interaction between non-polar solutes with polar surroundings exclusion is called hydrophobic interaction.

What method do scientists use to trace plant and animal extinctions through Earth's history

Answers

Answer:

Paleontology is the study of the history of life on Earth as based on fossils. Fossils are the remains of plants, animals, fungi, bacteria, and single-celled living things that have been replaced by rock material or impressions of organisms preserved in rock.

Explanation:

Because there are very few ways of directly estimating extinction rates, scientists and conservationists have used an indirect method called a “species-area relationship.” This method starts with the number of species found in a given area and then estimates how the number of species grows as the area expands.

HighLighter PopupUnderline Selected TextGreen Color HighlightOrange Color HighlightYellow Color HighlightBlue Color HighlightPink Color HighlightRemove Color Highlight A. Lemur B. Tarsier C. New World monkey D. Old World monkey

Answers

Answer:

C

Explanation:yeah

The correct answer is New World monkey as is observed in South America. It has a prehensile tail, spends most of its time in the trees, and is fairly small.

On one hand, a few species of New World monkeys own prehensile tails, which means they are able to use their tails to understand or maintain directly to objects (2). Their tails can resource those monkeys in locating and consuming meals withinside the cover in addition to transferring among the trees, as their tails offer greater help and balance.

The formal time period for the taxonomic organization containing all of the New World Monkeys (NWMs) is Platyrrhini. The NWMs diverged from the Old World monkeys and apes (Catarrhini) round forty million years ago (Perelman et al. 2011). Ancestral species are idea to have migrated to the Americas on rafts of plants or through island hopping (Fleagle 2013). The extant species of NWMs are presently labeled into 5 families, twenty genera, 156 species, and 204 taxa. However, the taxonomy of numerous taxa is debated withinside the literature and, therefore, this type is concern to change.

What is the New World monkey living area?

Many of the monkeys scampering across the forests of Central and South America have some thing unique on their butts-- a further hand. Well, now no longer exactly. It's a prehensile tail-- a greedy appendage that enables the animals navigate the tall and treacherous cover on the lookout for end result and leaves .

Hence concluded that the New World monkey have a prehensile tail, spends most of its time in the trees, and is fairly small.

(These were the corresponding textbook pages, if needed) Please read the following from the textbook Environmental Science:
7th Edition - Chapter 17
9th Edition - Chapter 14

Answers

Answer:

Advantages of following the soft path, the argument here is alternative sources of power such as hydropower, geothermal energy , wind energy , and photovoltaic cells must be developed. This provides a alternative source to remain in a healthy environment and also function as the society we currently live in using the hard path.  Disadvantages of following the hard path result with future generations fearing over the irreversible damage of climate change and the damage done to our atmosphere. The hard path argue that we should continue to operate in the future as we have in the past, except more efficiently. This is close to impossible and will only continue the negative effects the hard path( the path we have been following) results in. The major shift determines the outcome of this world, the futures worries or reliefs and ultimately the survival of humans.

5. C. 2; 7; 9.5

Explanation:

The image attached to this question shows a graphical representation of the pH ranges for three enzymes. According to the image;

- Enzyme 1 reached its peak reaction rate at pH 2 (acidic)

- Enzyme 2 reached its peak reaction rate at pH 7 (neutral)

- Enzyme 3 reached its peak reaction rate at pH 9.5 (basic)

This result means that enzymes 1, 2 and 3 will work well and effectively at an acidic, neutral and alkaline environment respectively. Likewise, the optimal pH level for enzymes 1, 2 and 3 are 2; 7; and 9.5 respectively.

How are genetic mutations passed from parent to offspring?

Answers

Answer:

Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. There are also nonhereditary mutations that occur in cells outside of the germ line, which are called somatic mutations.

I hope it's helpful!

Answer:

★ Mutated gametes (sex cells) fuse to create offspring.

Genetic mutations or germline mutations can be defined as a permanent change in the DNA sequence of germ cells (cells, which form ovum and sperm). These mutations can pass from one generation to other when a mutated sperm or mutated oocyte (gametes) get fertilized with another oocyte or sperm.

A germline mutation, present in a single-celled zygote will present in all cells of a muticellular organism, a single-celled zygote divides and produces all of the cells in that organism.
