Evolution Quick Check
Which of the following principles is NOT part of Darwin's theory of evolution by natural selection?

Answer and Explanation:

Regarding genetics, the results of the study show that the mother's genetic material does not influence the behavior of rats in times of stress or in the biological responses of rats to these stressful moments. This is because the mice inherited their mothers' genes, but did not show the same results in a stressful situation when they were raised with different mothers.

Regarding epigenetics, however, we can see that the mothers' behavior in relation to the care of rats managed to provoke epigenetic changes that prevented or stimulated the expression of genes linked to stress, in these rats. The rats that were raised with attentive mothers showed a low expression of stress-linked genes, regardless of the biological mother they had. In addition, it is possible to notice that this modification is permanent, since the rats presented this same type of response throughout their lives.

Answer:

Handwashing with soap removes germs from hands. This helps prevent infections because People frequently touch their eyes, nose, and mouth without even realizing it. Germs can get into the body through those said body parts and make us sick.

Answer:

bacteria and archaea

Explanation: Only the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes—pro means before and kary means nucleus

Answer:

The characteristic of daphnia which allows the population to adapt to the environmental change is the short generation time.

Explanation:

As evident from the text, the maturity comes in 5 to 10 days and they reproduce for the next 2 months at a rate of 100 eggs every 3/4 days. This is a short generation time which makes the evolutionary changes easy and less time-consuming to incorporate.

Answer:

There isn't wind all the time, so wind being used as a major energy source is very unlikely.

Answer:

there isnt always a lot of wind so it wouldnt be a reliable energy source

Explanation:

Answer:

Carbon dioxide, CO2, is a chemical compound composed of two oxygen atoms and one carbon atom.

Explanation:

Answer: No number means one atom. For CO2 there is one atom of carbon and two atoms of oxygen. For H2O, there is one atom of oxygen and two atoms of hydrogen. A molecule can be made of only one type of atom.

Answer:

Cellulose - It is described as a complex carbohydrate that forms the main constituent of the cell wall in most plants and is important in the manufacture of numerous products like pharmaceuticals, textiles, etc.

Chlorophyll - Any of a group of green pigments that are found in the chloroplasts of plants and in other photosynthetic organisms such as cyanobacteria.

Chloroplast - An organelle found in the cells of green plants and in photosynthetic algae, where photosynthesis takes place.  

Bryophyte - Any plant of the division Bryophyta, defined "sensu lato" to comprise the mosses, liverworts, and hornworts, and corresponding to all embryophytes that are not vascular plants.

Pterophyte - It is characterized as any fern(seedless plant) that is a division of Pteridophyta.

Gymnosperm - Any plant such as a conifer whose seeds are not enclosed in an ovary or those who don't bear seeds or fruits. Example; Cycads.

Cone - A cone-shaped flower head of various plants like banksias and proteas.

Angiosperm - Any flowering plant characterized by having ovules enclosed in an ovary and thus, produces fruits, as well as, seeds.

Flower - A reproductive structure in angiosperms and often conspicuously colorful and typically including sepals, petals, and either or both stamens and/or a pistil.

Cuticle - A noncellular protective covering outside the many invertebrates and plants.

Vascular tissue - The complex tissues that consist of various cell types and primarily responsible for transporting liquid and other nutrients throughout the plant or animal body.

Xylem - A vascular tissue in the land plants primarily responsible for the distribution of water and minerals that are taken up by the roots and also the key component of the wood.

Phloem - A vascular tissue in land plants primarily responsible for the distribution of sugars and the nutrients manufactured in the shoot.

Roots - The part of the plant which is generally underground that anchors and supports the plant body. It absorbs and stores water and nutrients, and in some plants is able to perform vegetative propagation.

Root hairs - The rhizoid of a vascular plant or a tabular outgrowth of a trichoblast, hair-forming cell on the epidermis of a plant root.

Stems - The above-ground stalk of a vascular plant that supports individual parts of a plant like leaves, flower, fruits, etc.

Leaves - The green and flat organ that represents the most prominent feature of the most vegetative plants.

Photosynthesis - The process by which plants and other photoautotrophs convert light energy into chemical energy. For example; Plants use air, water, along with sunlight to synthesize their food(carbohydrates and waste oxygen).

i did this in 6th grade and i think there is no chance because the thin haired woman has a non-dominant allele and the full haired man does have a strong  allele. so, the man has the dominant gene

Answer:

A

Explanation:

The sun produces two forms of eney.. which are mainly .. light and heat

Answer:

3.1.1 Division of the cytoplasm - Cytokinesis

3.1.2 Uncontrolled cell growth - Cancer

3.1.3 Chromatids lined up at equator of cell - Metaphase

3.1.4 Chromatids joined at this point - Centromere

3.1.5 Mass of cancerous cells - Tumor

3.1.6 Skin cancer - Carcinoma

3.1.7 Growth and mitosis - Meristematic

3.1.8 Cancer causing factors - Carcinogens

3.1.9 Cancer cells that do not spread - Benign

3.1.10 Replicated half of a chromosome - Chromatid

Explanation:

The division of the cytoplasm is known as Cytokinesis. It occurs during the later part of the division of the nucleus in both mitosis and meiosis. In Cytokinesis, the cytoplasm of a single parent cell divides in two to produce two daughter cells.

Cancer is a disease condition that results when the growth and division of cells is uncontrolled. It occurs as a result of changes to the DNA either due to environmental factors or heredity factors.

Metaphase is one of the four stages in mitosis. During mitosis, the chromatids which are joined at the centelomere line up at the middle or equator of the cell.

Centromere is a region in the chromosome in which sister chromatids are joined together to form a short and a long arm of the chromosome.

A tumour is a swelling of a part of the body due to the abnormal growth of cells in that part of the body. A tumour may have the ability to spread or not.

Cancers that originate in the skin or tissues lining organs is known as carcinomas.

In plants, meristematic tissues are responsible for growth as they consist of actively dividing or mitotic cells. Meristematic cells are present at the tips of roots,stem and branches.

Carcinogens are agents or factors that are able to cause cancers. They include such agents like chemicals, electromagnetic radiations, some viruses, lifestyle factors, etc.

Benign tumours refers to growths in tissues or organs of the body which are non-cancerous as they do not spread to other tissues or organs in the body.

A chromatid is one-half of a replicated chromosome present in the nucleus of the cell. Two chromatids are joined together at the centromere to form the chromosome.

Explanation:

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Answer:

The process by which plants turn carbondioxide and water into carbohydrates and oxygen using  light energy trapped by chlorophyll, is called photosynthesis.

Answer:

respiratory system

Explanation:

The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles. These passageways then evolve into tiny air sacs called alveoli, which is the site of oxygen and carbon dioxide exchange in the respiratory system.

Answer:

Evolution

Explanation:

The concept of growth and development and changes , or the hypothesis that species have evolved and formed from previous species, is referred to as evolution. Biological evolution of an organism' features changing over many generations by natural selection. Genetic diversity is needed for evolution to occur.
