Answer:
The answer is Spanish flu
Answer:
H1N1 virus with genes of avian origin
Explanation:
The outbreak was caused by an influenza type, where the subtype of it is know as H1N1 virus.(. Characterization of five of the eight RNA segments of the 1918 influenza virus indicates that it was the common ancestor of both subsequent human and swine H1N1 lineages, and experiments testing models of virulence using reverse genetics approaches with 1918 influenza genes have begun in hopes of identifying genetic features that confer virulence in humans.....

the piece of mRNA: AUG UCU UGC
A
val-ser-leu
B
meth-ala-leu
с
thre-leu-gly
D
meth-ser-cys
Answer: D
Explanation:
Okay so look at the diagram. Start from the middle and work your way out.
AUG: I find A in the middle (the first four) and then go to the part of the diagram that has U right under the last letter you had, so A. And do the same for U, and you should get methionine.
Repeat this process for the other two.
Explain why a topographic map has a key.
Topographic maps represent the locations of geographical features, such as hills and valleys.
What do you mean by topographic maps?Topographic maps use contour lines to show different elevations on a map. A contour line is a type of isoline; in this case, a line of equal elevation.
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief features, usually using contour lines.
A topographic map is a detailed and accurate illustration of man-made and natural features on the ground such as roads, railways, power transmission lines, contours, elevations, rivers, lakes.

Answer:
Parasitism
Explanation:
This is because parasitism is a type of relationship that exist between organisms where one which is the predator feed on the prey thereby causing harm or injury or death to the prey. In the question, small frogs are the predators and insects are the prey, therefore the predators cause harm to the prey, meaning they only benefits from the farm they cause the prey.
Using the allele symbols in the table, identify the genotype of a guinea pig that is recessive for hair length, heterozygous for hair color, and homzygous dominant for hair texture.
Answer:
Hair length: hh
Hair color: Bb
Hair Texture: RR
Explanation:
In order for the recessive gene to show for hair length, two of the same alleles must be present, so, in this case, hh.
The question states "heterozygous for hair color." This tells you that the genotype will be Bb. Heterozygous means two of the different alleles. This is different from homzygous.
The question states "homzygous dominant for hair texture." This tells you that it will contain two of the same alleles. The question also tells you that it is homzygous dominant, which means there will be two of the same dominant alleles, so, RR.

The true statement about how early humans met their needs is : ( A ) The first humans moved around alot looking for food .
Way of life of Early humansIn order to survive early humans moved around like nomads in search of food and shelter most of the times because there was no formal or mechanized way of cultivating agricultural products for food.
As humans continued to advance in knowledge they started farming and rearing of animals but these were not done by early humans.

all plant bodies(root,stem and leaf) are externally covered by epidermis but why woody plant is covered by barks
Answer:
Bark comprises all the tissues surrounding the xylem in woody plants. Broadly, bark includes an inner and mostly living region and an outer, dead one. Of all plant structures, bark has the most complex anatomical structure and ontogenetic origin involving two (and often three) different meristems.
As to why, the bark adds layers to the inside ring of the vascular cambium, the outside is pushed outward. The cells die off, and the fibrous matrix of cellulose and lignin molecules remain. This hard structure forms the bark, and protects the tree or plant from many forms of damage.

Why is it important that the seedling’s true leaves grow quickly?HURRY IM BEING TIMED
to help disperse seeds to areas where they can grow
to shield the seedling from too much water or rain
to protect the seedling from receiving too much sunlight
to make food for the seedling’s continued growth
Answer:
The correct answer is - to make food for the seedling’s continued growth.
Explanation:
The true leaves that emerge from the seedlings are the leaves that are capable of performing photosynthesis and start generating food and energy. These support the plant for the rest of its life in terms of food and energy.
Seedlings grow from the soil, two leaves in beginning called cotyledons that are not the true leaves and not able to perform photosynthesis and generate their food for the seedling’s continued growth.

Answer:
share benefits equitably for improved quality of life.Explanation:
The ultimate goal of sustainable development is to meet current and future resource needs. Therefore, the correct option is B.
What is sustainable development?Sustainable development is the concept of meeting the demands of the present generation without compromising the ability of future generations to meet their own needs. It is a strategy to achieve economic growth and expansion while safeguarding social welfare, environment and both.
The idea of sustainable development acknowledges the interdependence of economic, social and environmental problems and the need to address them all simultaneously. Sustainable development aims at striking a balance between economic expansion, resource conservation and environmental protection. Additionally, it strives to advance social justice and raise the standard of living for all. Meeting current and future resource needs is the ultimate goal of sustainable development.

Help me past due Write down what you think will happen to the density of water if you add salt or sugar.
Answer:
If I add sugar or salt, the water's density will increase.
Explanation:
Density is the relation between mass and volume. We can represent it with the formula δ= m/v. Where δ stans for density, m for mass, v for volume.
If we add salt or sugar, we increase the mass, but the volume is the same. As a result, the density will increase.
We can use numbers to understand it better.
Suppose that before adding salt or sugar, the mass is 1 g and the volume is 1 l
δ= 1g/l1t
δ= 1 g/lt
Now, if we add sugar or salt, the mass increases. Suppose that we have 2g of mass and the volume is the same, 1l.
δ= 2g/1lt
δ= 2g/lt
We can see that the density increased when the mass increased.
