How is the ownership of the oceans resource Determined
Setler79 [48]

Answer:

technically its everyone's but isn't at the same time

Explanation:

The UN Convention on the Law of the Seas states the different rights and regulations regarding specific nations’ rights to oceans. For instance, coastal states have jurisdiction over the 12 nautical miles off their coastlines, and 200 nautical miles are reserved for specific states to utilize the oceanic materials, living and nonliving, in their zone. This can include fishing, the mining of minerals but also includes the obligation to protect the ocean and its biodiversity.

Eosin-methylene blue agar, or EMB, is a commonly used bacteriological medium for growing gram-negative bacteria from complex env
oksano4ka [1.4K]

Answer:

Differential and selective

Explanation:

A selective media is one used for growth of only selected microorganisms. Since this medium is using methylene blue to inhibit gram-positive bacteria and allowing the growth of gram-negative, then we can cathegorize it as selective. Selective growth media is also used in cell culture to ensure the survival or proliferation of cells with certain properties, such as antibiotic resistance or the ability to synthesize a certain metabolite, so the researchers can study or farm said metabolite or an specific reaction to an antibiotic.

Meanwhile, a differential media, also called indicator media, distinguish one microorganism type from another on the same media. This is done through biochemical characteristics which reacts to specific nutrients or indicators (neutral red, phenol red, eosin y, or methylene blue) added to the medium to visibly indicate the defining characteristics of a microorganism. Since this media is changing colors when the acidic concentration increases, it is a differential media as well.

2. In a classroom experiment, you ground up some spinach in distilled water and filtered the liquid onto a piece of filter paper
ivanzaharov [21]

Answer:

Mitochondria; cellular respiration.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

In a classroom experiment, you ground up some spinach in distilled water and filtered the liquid onto a piece of filter paper. The isolated organelles absorbed carbon dioxide and released oxygen. Thus, the cellular organelle which was most likely on the filter paper is mitochondria and the process it was performing is called cellular respiration.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP).

Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.

What is the genotype of the parent with orange eyes and white skin? (Note: orange eyes are recessive.)B=black eyes G=green skinb
kykrilka [37]

Answer:

D

Explanation:

Two genes are involved in this case: one coding for eye color and the other for skin color.

According to the question, the allele for Black eyes (B) is dominant over the allele for orange eyes (b) while on the other gene, the allele for green skin (G) is dominant over the allele for white skin (g).

This means both alleles for orange eyes (b) and white skin (g) are recessive i.e masked by their counterpart allele

Since they are recessive, they will only be phenotypically expressed if they are in their homozygous state. i.e same type of allele.

In this case, the parent has orange eyes and white skin i.e.both recessive traits

Therefore, the genotype will be bbgg.
