D. is a true statement.

Answer:

C. Mutations are all permanent. Mutations can occur in many types of cells, and contribute to genetic diversity. Not all mutations are caused by harmful chemicals, as there are many natural mutations in nature. However, mutations are not always passed on from parents to offspring.

17. How does the placement of the stamen in relationship to the pistil affect the way in which

the flower is fertilized?

Answers

Answer:

this placement increases the chances of pollination

Explanation:

Pollination refers to the process of transferring pollen grains from the male stamens of a flower to the female stigma. The stamens generally surround the pistil and they are composed of two structures: 1-the anther (produces male reproductive cells or pollen grains) and 2-filaments (supports the anthers). Moreover, the female pistil is generally located at the center of the flower and it is composed of three structures: stigma (a sticky bulb in the center of flower), ovary (contains female reproductive cells or ovules), style (supports the stigma). The arrangement of the plant's reproductive organs increases the chances of pollination: when a pollinator (e.g. bees) visits a stigma for nectar it has to go through the stamen and catch pollen that then carries to the stigma of the same flower (auto-pollination) or another flower (cross-pollination). Moreover, the flowers also have petals and sepals that help attract pollinators and protect the flower bud, respectively.

18. Brayden is trying to figure out how petal shape is determined in two different roses. In the pink
rose, the copies of the gene are the same as each other. In the yellow rose, the copies of the gene are
different from each other. How does this affect how many types of proteins there are in each petal
cell?
a
The pink rose has one type of protein for the petal shape feature. The yellow rose has two
types of protein for the petal shape feature.
b
The pink rose has one type of protein for the petal shape feature. The yellow rose has one
type of protein for the petal shape feature.
с
The pink rose has two types of protein for the petal shape feature. The yellow rose has two
types of protein for the petal shape feature.
d
It is impossible to say anything about proteins from the given information.

Answers

Answer:

Explanation:

they would have diffrent gene versions and protines to get their colors

In the pink rose, the copies of the gene are the same as each other, while the yellow rose has different copies, so it is concluded that the pink rose has one type of protein for the petal shape feature, while the yellow rose has two types of protein for the petal shape feature, as present in Option a.

What is the petal shape dependent on?

Generally, the characters are dependent on the genes that are present in the DNA; either the gene variants, such as the alleles, show pure dominance or they combine to produce the effect, and here the pink rose petal has the same alleles so they will express the single protein while the yellow has different alleles so it has the chance of the two proteins.

Hence, in the pink rose, the copies of the gene are the same as each other, while the yellow rose has different copies, so it is concluded that the pink rose has one type of protein for the petal shape feature, while the yellow rose has two types of protein for the petal shape feature, as present in Option a.

Which of the following is true regarding Darwin's theory of evolution?
A. Acquired traits are always passed on to the offspring
B. Organisms develop favorable adaptations based on a need
C. Pure chance determines which species evolve
D. Individuals pass on adaptations to their offspring, due to natural selection

Answers

Answer:D

Explanation:

Evolution

Individuals pass on adaptations to their offspring, due to natural selection. The correct option is D.

What is Darwin's theory of evolution?

The English naturalist Charles Darwin and others developed the Darwinism theory of biological evolution, which contends that all species of organisms arise and develop through the natural selection of minute, inherited variations that improve the individual's capacity for competition, survival, and reproduction.

Darwin claimed that all species share a common origin, that species can change through time, and that new species develop from existing ones.

Charles Darwin, a naturalist of the 19th century, investigated the theory of natural selection.

Natural selection provides an explanation for how a species' genetic features might evolve through time. This could result in speciation, or the creation of a new, separate species.

Thus, the correct option is D.

Contrast the contraction of the a disease by the environmental, heredity/genetic and pathogenic pathways.

Answers

Answer:

Explanation:

Contraction of a disease by the environment, the environment is said to influence something certain traits either by amplifying them or prevent them from being expressed. Some disease tends to strive in environment that is favorable while some disease don't find expression where the environment is not conducive even though they are presents in the gene of the individual. Environment could include family, area where the individual lives, food, peer

While Contraction of disease that are heredity/genetic and having pathogenic pathways is high this is because any disease that is hereditary can be passed to successive generation through the inheritance of such gene from the parents this increase the likelihood of reoccurrence of such disease in a family where the parents has it.

A tornado strips out a section of a forest. What type of succession is this? Why?

Answers

Answer:

Secondary succession

Explanation:

A secondary succession is when a type of disturbance happens when there is already soil present. In this case, it has already started out with a forest (including plants, trees, and wildlife). Other examples of a secondary succession include a wildfire, hurricane, flood, or human destruction.

This is different from a primary succession. A primary succession occurs when there is no soil present.

What 2 things do cells need in order to create energy

Answers

Answer:Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.

Explanation:

Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs.

In addition to mutations, genetic variation can also arise during the formation of gametes during meiosis. During meiosis I, homologous chromosomes can randomly exchange segments, in a process called crossing-over. This trading changes the order of the genes in the DNA and on the chromosomes. Exchange material is integrated into the rest of the chromosomes DNA. Each chromosome loses some DNA and gains some DNA. As a result, there are more genotypes in the offspring. 2. What function does recombination by crossing-over have in genetic variation

Answers

Answer:

Crossing over ensures that organisms of the same parents have differences in genetic content making them unique in one way or the other.

Explanation:

This question is describing the process of crossing over, which occurs only during prophase I of meiosis. During the process of crossing over, alleles of a gene are exchanged between non-sister chromatids of homologous chromosomes (mother and father chromosomes).

Hence, a unique GAMETE that has been genetically recombined will be formed. When these gametes are fertilized (egg) or fertilizes (sperm), organisms that are genetically different from their parents are produced. This ensures genetic variation, which is a difference in the genetic content of organisms.
