The ovary is the part of the female reproductive system that produces ova.
The ovary is an organ located in the female reproductive system that produces female reproductive cells or ova. The ovary is often paired and are firm, smooth and about the size of an almond. The ovaries are held by a membrane next to the uterus on both side of the lower abdomen. When an ovum is produced, it moves into the uterus through the fallopian tube, where it may be fertilized by a sperm. The ovary also secretes various hormones such as estrogen and progesterone that perform major roles in the menstrual cycle and fertility.
Answer:
A carbon footprint deals with the resource usage but focuses strictly on the greenhouse gases released due to burning of fossil fuels. Greenhouse gas calculation make up a portion of an ecological footprint. An ecological footprint compares the total resources people consume with the land and water area that is needed to replace those resources, it measures the demand human populations put on nature. Both calculations illustrate the impact of human activity on the environment.

Answer:
chromosomes
Explanation:
k12 answer by the way
Answer:
1. What is the relationship between chromosomes and DNA? The chromosome is a molecule formed by a chain of DNA associated with proteins. Together, they form a group of molecules directly responsible for heredity.
2. What is heredity? It is the biological process where the genes present in a DNA are transmitted by parents to their children, through the division of gametes. These genes carry the codes that form the genotypic and phenotypic characteristics, which allows a similarity between parents and children to occur.
3. What is the role of proteins associated with the DNA molecule that makes up the gene? Proteins are responsible for keeping the DNA line tightly compressed, maintaining the chromosome structure. In addition, they control the activities of the genes present in this DNA molecule, being essential in maintaining heredity.
4. How do chromosomes participate in gene transmission? As mentioned above, genes are part of DNA and DNA is the molecule that makes up chromosomes, in this case, chromosomes are molecules loaded with genes. In the human body, cells have 46 pairs of chromosomes, with the exception of gametes that have half that number. During the reproductive process, the gametes (reproductive cells) divide and produce a new being. The mother's gametes unite with the father's gametes to form a new being. Each gamete has 23 chromosomes, which contain the genes responsible for transmitting the characteristics.
Explanation:
b. heterotrophs.
c. thylakoids.
d. plants.
Answer: Heterotrophs
Explanation:
Organism that cannot make their own food and depends on the external sources for its energy are known as the heterotrophs.
They are dependent on the other organisms for their energy. They feed on the plants or animals for their energy.
Other than plants all the other organisms are dependent on food from other sources as they lack the ability to make food by their own.
Heterotrophs are the organisms that feed on other organisms to get energy to survive. Option B, Heterotrophs.
Organisms are classified into autotrophs and heterotrophs depending on how they get energy.
Heterotrophs need to feed on other organisms to get the necessary energy to survive. They do not produce their own food as producers do.
Depending on the food chain, heterotrophs might be either primary, secondary, tertiary consumers, and so on.
Also, depending on their source of food, they might be either herbivores (if they feed on plants) or carnivores (if they feed on animals). Omnivores can feed either on plants or animals.
In the exposed example, the organisms that cannot make their own food and must obtain energy from external sources are called heterotrophs.
The correct option is b. Heterotrophs

Answer: fat
Explanation:
Carbohydrates, fats and proteins are among the major nutrients in the food component.
Hence, fat gives you the most energy .
