Identify the other key structures that indicate the probable origin of a chloroplast

Answers

Answer 1
Chroloplasts Acts as a main role in photosynthesis.Chloroplasts likely orginated from engulfed "prokaryotes" that once lived as independent organisms. They are also considered to be originated from "cyanobacteria" through endosymbiosis—when a eukaryotic cell engulfed a photosynthesizing cyanobacterium that became a permanent resident in the cell.

The inability of an organism to produce certain proteins can occur when an organism is lacking an enzyme needed to combine

Answers

 Living organisms have enzymes which are capable of linking amino acids together by creating a peptide bond between the amino acids. This process takes place in the A and P site of ribosomes in the cell during translation.

One such enzyme is called peptidyl transferase. If an organism lacks such an enzyme,  synthesis of the proteins catalyzed by that particular enzyme in its cells will not take place. If amino acids cannot be joined together, then a polypeptide chain, which forms the primary structure of the protein will not be formed.

Which of these minerals would you use to make wallboard for the interior walls of your house?

Answers

It is the gypsum. Gypsum is a delicate sulfate mineral made out of calcium sulfate dihydrate, with the synthetic recipe CaSO. 4· 2H2O. It is broadly mined and is utilized as a compost, and as the principle constituent in many types of mortar, writing board chalk and wallboard.

The mineral used to make wallboard for house interior walls is gypsum (option c).

To make wallboard for the interior walls of a house, you would use the mineral gypsum (option c). Gypsum, or calcium sulfate dihydrate, is a sulfate mineral that is used in construction materials such as plaster and drywall. Wallboard made from gypsum is commonly referred to as sheetrock.

If you were building a house with a basement, you would typically prefer the dominant clay mineral of the soil on your lot to be kaolinite rather than bentonite. Kaolinite is a clay mineral that is less prone to swelling and water absorption compared to bentonite, making it more stable and preferable for a foundation.

Because it ........................., the brain's HYPOTHALAMUS ultimately controls the endocrine system.
The hypothalamus is the part of the brain that controls the endocrine system, it does this by linking up the nervous and the endocrine system via the pituitary gland. Hypothalamus functions by releasing hormones which either inhibit or stimulate production of hormones in the anterior pituitray gland.

The brain's hypothalamus controls the endocrine system by regulating the pituitary gland, which is the master gland responsible for the secretion of hormones that affect other glands and bodily functions.

Because it controls the pituitary gland, the brain's hypothalamus ultimately controls the endocrine system. The hypothalamus is a critical part of the brain that provides a link between the nervous and endocrine systems by controlling the pituitary gland, also known as the "master gland".

This master gland secretes various hormones that influence other endocrine glands such as the thyroid gland and pancreas, which are responsible for essential physiological processes like growth, metabolism, sexual maturation, reproduction, body temperature, and blood pressure regulation. The pituitary gland produces several hormones, including growth hormone, endorphins for pain relief, and hormones that regulate fluid levels in the body, exemplifying its central role in the body's hormonal regulation.

The word part​ "brady-" in​ "bradycardia" is considered what part of a medical​ term?

Answers

brady means slow.it is a greek word


The correct term for the word part ""brady-"" in ""bradycardia"" is a prefix.

In medical terminology, words are often constructed from a combination of prefixes, suffixes, and root words.

The prefix ""brady-"" is derived from the Greek word ""bradys,"" which means slow. It is used in medical terms to indicate a condition characterized by slowness or a reduced rate. In the case of ""bradycardia,"" the term refers to an abnormally slow heart rate. The prefix ""brady-"" combined with the root word ""cardia,"" which pertains to the heart, clearly describes the condition as a slow heart rate.

Prefixes are an essential component of medical terminology as they modify the meaning of the root word and help to specify the exact nature of the medical condition or procedure being described.

Explain how a GIS can model the relationship between a natural resource and an observed change. Include an example of a change in the availability of a specific natural resource and a specific observation of nature.

Answers

Answer:

Water in a river can be traced through GIS

Explanation:

With the improvement in observational tool, GIS technique has proved exceptionally helpful in tracing the natural resources. The pixels number and color help us to trace the changes in quantity as well as quality.

For example -

Suppose,  a river and its channel is being traced through GIS.

In year 1991, the number of pixels covering a certain area and of sky blue color signifies large volume , area of water and its good quality respectively

However, after 10 years  image of same are may show a change in previous observation such as reduction in number of blue pixels and also change in color from blue to red signifying increase in pollution level.

GIS can be used in analyzing the data that are related to the place where a natural resource is gotten.

A geographic information system is important as it helps in the capturing, storage, and display of the data that are related to a particular position on the surface of the Earth.

When natural resources are found in an area, the geographic information system can be used in getting further information about the area. A geographic information system can also be used in the management of natural resources as they give spatial data which are necessary to know the disasters that have taken place in such an area before.

In conclusion, GIS is beneficial in natural resource management.

Hello! Succession is not really harmful to ecosystems and it’s not a one-time event, because things come and go overtime. Therefore, it’s not A or D. It is necessary for ecosystem recovery, because it’s needed to continue on with things, just like families reproduce to make family continue. It’s not that bad. It’s just a natural process that happens. The answer is B: natural recovery process.

Succession is a natural recovery process. So, the correct option is (B).

What is an ecosystem?

Ecosystem is the study of interaction between population or organisms and the environment. It is the structural and functional unit of ecology.

Examples of ecosystems are: aquatic ecosystem, coral reef, desert, forest, human ecosystem, littoral zone, marine ecosystem, rainforest, savanna, urban ecosystem and others.

It consists of two components:

1. Abiotic components

2. Biotic components

1. Abiotic components- It consists of non-living components. For Eg., rocks, soil, minerals, water sources, and the local atmosphere.

2. Biotic Components- it consists of living components which are of two types- Prokaryotic and eukaryotic cells. Eukaryotes having membrane bound organelles while prokaryotes lack membrane bound organelles.

Thus, succession is a natural recovery process. So, the correct option is (B).

What advantages do flowers give angiosperms over gymnosperms?

Answers

Hey! Look what I found online.

In general, it makes the angiosperms more efficient in pollination and, therefore, in producing seeds. Most angiosperms have perfect or bisexual flowers, that is, both the male and female reproductive organs are borne on the same flower while these are separated in the gymnosperms. In the conifers which are gymnosperms, thousands of pollen grains will be needed to pollinate one female. The pollens are carried by the wind and having one pollen land exactly on the stamen is quite an impossibility. 

Many angiosperms have colorful petals. This attracts the insects and birds. As they move from one flower to another, they deposit the pollens on the stigma of another flower. The nectar that angiospermous flowers produce and the aroma emitted play the same role.
