Answer:
The Earth's tilted axis causes seasons. During different parts of the year, the Earth recieves the sun's rays directly. It's summer in the Northern Hemisphere. When the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

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.
The organism in the photo is a daphnia, or water flea. Daphnia are tiny aquatic organisms that live in most freshwater habitats. Adults range from less than 1 to 5 mm in length. They are good swimmers and eat mostly algae. Daphnia become mature at 5 to 10 days, and an adult female can produce up to 100 eggs every 3 or 4 days during its 2-month life span. When harmful algae rapidly increase in the daphnia environment, daphnia can develop adaptations to tolerate the negative effects of the algae within 10 years. What characteristic of the daphnia allows the population to adapt to environmental change
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.

If a thin haired woman (bb) has a child with a full haired man (B-), then what is the chance each of their boys will be bald?
Please no files that I have to download
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

what allows oxygen to pass into your blood?
branliest.
Answer:
The alveoli are responsible for receiving oxygen and transferring it to the blood. The alveoli are surrounded by capillaries, which are tiny blood vessels. Both the alveoli and the capillaries have very thin walls, allowing oxygen to travel from the alveoli to the blood.
I'll mark brainliest

Select one:
A. it will decrease.
B. It will remain the same.
C. it will increase very fast.
D. It will increase slowly.

species change over time through a?
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.
Lilly and her lab partner, Alberto are investigating factors that influence the rate of photosynthesis. They know that any change to the reactants in photosynthesis could have an effect on the production of glucose and oxygen. In doing some research, the pair comes across the data shown above. They decide to brainstorm possible variables they could change in their experiment that could increase the rate of photosynthesis. Evaluate their list of possibilities. Based on the data and your knowledge of photosynthesis, what would you advise Lilly and Alberto to consider changing in their experiment if they wanted to increase the rate of photosynthesis? Choose ALL that apply.

A scientific study demonstrated that rat mothering behavior impacts the stress response in their pups. Rats that were born and grew up with attentive mothers showed low activation of stress-response genes later in life, while rats with inattentive mothers had high activation of stress-response genes in the same situation. An additional study that swapped the pups at birth (i.e., rats born to inattentive mothers grew up with attentive mothers and vice versa) showed the same positive effect of attentive mothering. How do genetics and/or epigenetics explain the results of this study
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.

Why do we exhale more carbon dioxide than we inhale?
Answer:
When we exhale, we breathe out less oxygen but more carbon dioxide than we inhale. The carbon we breathe out as carbon dioxide comes from the carbon in the food we eat. The carbon dioxide is dissolved in the blood, carried to the lungs by the circulation, and breathed out.
Answer:
because our bodies take in O and put out CO2
Explanation:
O is Oxygen
and CO2 is Carbon dioxide
