Answer:

Genetic mutations are passed from parent to offspring by mutated gametes (sex cells) which are fuse to create offspring.

Explanation:

Genetic mutations or germline mutations can be defined as 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 other oocyte or sperm.

When a single celled zygote containing genetic mutations divides then this mutation spreads to the whole cells of an organism.

DNA that is only passed on from mothers to their children is stored in mitochondria,Mutations in mitochondrial DNA (mtDNA) are important causes of various types of diseases.

THUS THE GENETIC MUTATIONS ARE PASSED FROM PARENTS TO OFFSPRING BY MUTATED GAMETES ,FUSING TO CREATE OFFSPRING.

The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations. A single germ line mutation can have a range of effects: No change occurs in phenotype.

1. The effect of initial population sizes on the growth of populations of an organism was

ella [17]

When graphing data, we must consider the variables, label axes, define units of measure. In this case, variables are initial population size / final population size, showing an directly proportional relationship.

-------------------------------------

We need to construct a graph illustrating the data in the table.

We can make a dispersion graph. To do it, we need to define variables.

Since we want to know how different initial population sizes affect population growth,

the independent variable is the initial population size
the dependent variable is the final population size (after 24 hours)

The final population size depends on the initial population size. This is, the number of individuals at the beginning will influence the final number of individuals.

Initial population sizes ⇒X horizontal ax ⇒Unit: Number of individuals
Final population sizes ⇒ Y vertical ax ⇒ Unit: Number of individuals

By making a dispersion graph, we can represent the effect of the varying initial population sizes on the final population sizes. We can compare these effects and observe how populations grow as the N₀ increases.

We can also choose a bar graph. In this way, we can compare initial and final population sizes.

This graph will show populations and two bars per population.

Blue bar ⇒N₀⇒ Initial population size
Red bar ⇒N₁ ⇒ Final population size

Different populations ⇒ 1, 2, 3, 4, 5 ⇒ Represented in the X horizontal ax

The number of individuals ⇒ from 1 to 324 ⇒ Represented in the Y vertical ax.

By making a bar graph, we can represent initial and final population sizes and compare them. The population that begins with 1 individual, after 24 hours has 4 individuals. The population that begins with 3 individuals, ends with 9 individuals. And so on.

No matter which graph you choose, you will observe a directly proportional relationship between both variables. The bigger is the initial population size, the bigger it ends after 24 hs.

dalvyx [7]

Answer:

True. You can get vitamin A as "preformed vitamin A" which is already active and/or you can get vitamin A as carotenoids which the body can turn into active vitamin A.

Explanation:

There are two different types of vitamin A that can be obtained from food:

1. Preformed vitamin A, which is already active, is found in animal products such as beef, fish, poultry and dairy products.

2. Provitamin A, which is the inactive form, is found in plant-based foods, such as fruits and vegetables. The most common type of provitamin A is β-carotene, which is a carotenoid that the body can turn into active vitamin A via an enzyme named β-carotene 15,15'-monooxygenase.
