What is an angiosperm? Provide 2 examples. PLEASEE

Answers

Answer: Angiosperms represent approximately 80 percent of all known living green plants. Examples range from the common dandelion to ancient flowers such as magnolias. Angiosperms also make up the vast majority of all plant foods we eat. (Ex. grains, vegetables, and fruits.) The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary The ovary itself is usually enclosed in a flower, that part of the angiospermous plant that contains the male or female reproductive organs or both. fruits are derived from the maturing floral organs of the angiospermous plant and are therefore characteristic of angiosperms.

Beaches are monitored to protect public health. Waterborne pathogens can cause illnesses. Which of the following is not a common type of pathogen at the beach?

Bacteria
Protozoa
Viruses
Worms

Answers

ALL these microorganisms can represent common types of pathogens at the beach. In consequence, it is imperative to take precaution measures to avoid infections.

The sand at the beach may contain dog feces, which is known to transport Toxocara canis, a parasite roundworm able to infect humans.

Moreover, samples of beach sand may also contain different types of pathogenic bacteria (e.g., Staphylococcus species, E. coli, Enterobacteriacea, etc) and viruses (e.g., enteroviruses, hepatitis A, Norwalk viruses, reoviruses, rotaviruses, etc).

In consequence, it is imperative to wash hands with soap and water when touching beach sand that is suspected to be contaminated.

Finally, marine water may also be contaminated with different zoonotic protozoa such as, among others, Giardia, Cryptosporidium and Toxoplasma.

what are the four final cell types produced by oogenesis in the female

Answers

Answer:

Oogenesis in the female is the process that produces fertile eggs, ready for fertilisation by the male sperm. Each egg has only one of each of the 23 human chromosomes - normal body cells have a pair of each, having 46 chromosomes in total.

To produce egg cells, the process of oogenesis takes place in the female ovary. Progenitor cells divide through a cell division process called meoisis, which is also known as a reduction division.

Instead of one cell splitting into two identical cells, four cells are produced which have half the normal number of chromosomes - they are described as being haploid.

The four cells are all genetically different because the process of meiosis involves cross overs of the chromosomes during division, so mixing up the genes inherited from the woman's mother and the woman's father. This variation produces fitter offspring as it widens the genetic variation that is possible.Explanation:

in the ecosystem energy budget, primary productivity is like _____.

Answers

Answer: Income

Explanation:

In the ecosystem energy budget, primary productivity is like income. This is because primary production is the way in which energy enters an ecosystem.

I hope this helps :}

In the ecosystem energy budget, primary productivity is like income. Therefore, the correct option is B.

What is primary productivity?

Primary productivity is the rate at which organic matter is produced by photosynthesis in an ecosystem. It represents the energy that enters the ecosystem from the sun and is available for consumption by other organisms. Therefore, like income, primary productivity is a source of energy that is available to be “spent” by organisms in the ecosystem.

Option A, debt, is not an appropriate analogy for primary productivity, as it implies a negative balance. Option C, the interest rate, is also not an appropriate analogy, as it does not represent a source of energy but rather a factor that affects the rate of exchange of energy. Option D, spending, is a closer analogy, but it does not capture the fact that primary productivity is a source of energy, rather than an action that depletes energy. Therefore, the correct option is B.
