Explanation:
, where should the capillaries and lymphatic vessels be placed tomaximize the absorption of nutrients from food
Answer:
They should be placed in the small and large intestine.
Explanation:
The small and large intestine is the part of our digestive system that absorbs the nutrients from food. Previous to this step, the food went through the mouth, the esophagus, and the stomach. In those places, it was processed so that the intestines could absorb the nutrients from the food easily/
For nutrients to be absorbed, they should be in stretch contact with the intestines' walls where the smallest arteries, which are called capillaries, are present and will take the nutrients into its interior where the blood is. Also, the intestines have lymphatic vessels. These ones will protect our body from any antigen since they are part of our immune system.

Looking at the map below. predict what type of boundary is present and the resulting features of the boundary at the Philippine Plate and the Eurasian Plate
Eurasian Plate
Answer:
The answer is A - Convergent boundary resulting in earthquakes and volcanic activity
Explanation:
In map, Convergent boundary resulting in earthquakes and volcanic activity.
What do you mean by convergent boundary?A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction.
The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone. A convergent boundary is an area on Earth where two or more lithospheric plates collide.
Another form of convergent boundary is a collision where two continental plates meet head-on. Since neither plate is stronger than the other, they crumple and are pushed up.

Explain the differences between DNA and RNA.
Answer:
Explanation:
The difference between DNA and RNA is.....
DNA = Double-stranded
RNA = Singer-stranded
DNA = The sugar moiety is deoxy ribose
RNA = Ribose is the main sugar
DNA = Thymine is always there, but uracil is never found
RNA = Pyrimidine components differ. Thymine is never found
DNA = It follows Chargaffs rule (since it's double stranded)
RNA = Doesn't follow Chargaffs rule (since it's single stranded)

Bleeding from a small cut soon stops due to the release of
enzymes from
1) Platelets
2) Activated Antibodies
3) Hemoglobin
4) White blood cells
Answer: 4) white blood cells
Explanation:
The bleeding from a small cut soon stops due to the release of platelets. Hence, option 1 is the correct answer. These are cell fragments of megakaryocytes.
What is a blood clot?When there is a cut, blood comes out of that organ. To prevent blood loss, the body has certain mechanisms. This mechanism is called blood clotting.
In the blood, different cells are present. Red blood cells (RBC), white blood cells (WBC), and megakaryocytes are present in the blood. The red blood cells supply oxygen to the different tissues. It consists of hemoglobin. The white blood cells protect the body from pathogens. Eosinophils, neutrophils, basophils, monocytes, etc. are white blood cells ( WBC)
Megakaryocytes are the cells that form platelets. These platelets are cell fragments of megakaryocytes. When a cut occurs, these platelets come to the site along with other clotting factors such as fibrinogen to form a network-like structure. Due to this network, the blood cells can't come out, and blood loss stops.
Hence, option 1 is the correct answer as platelets prevents the blood loss. Other options are incorrect.

Explanation:
Why I know this because I just took the test
Based on the information in the graph Australia's population is currently growing the least.
How much has Australia's population grown in the last 50 years?Australia's population almost doubled in the past 50 years, from 13.1 million in 1971 to 25.7 million in 2021. But more remarkable is that this record population growth has exceeded all forecasts.
Why Australia is underpopulated?Australia has an average population density of 3.4 persons per square kilometre of total land area, which makes it one of the most sparsely populated countries in the world. This is generally attributed to the semi-arid and desert geography of much of the interior of the country.

Which of the following organisms is likely to be in the lowest trophic level
of an ocean food chain?
O Leopard Seal
O Penguin
O Krill
O Plankton
O Fish
Answer: Plankton
Explanation:
Plankton are small organisms that exist in water and are too weak to swim against the currents of the ocean and the seas. This leads to them going wherever the currents take them. Plankton can be either plants or animals.
Of the organisms listed, they are on the lowest trophic level and provide a source of food to other organisms of different sizes ranging from krill to whales.
Which statement below best describes the function of the nucleus?
Answers:
a) Stores cells wastes and destructive enzymes
b) contains hereditary information and controls most of heredity and cell processes
c) directs cell division in animal cells
d) controls water pressure and stores wastes
Answer:
b) contains hereditary information and controls most of heredity and cell processes
it contains and protects DNA
Explanation:
The statement that best describes the function of the nucleus is that it contains hereditary information and controls most of the heredity and cell processes.
Cells are recognized as the building blocks that make up organisms. These cells are further made up of several structures that are well defined. Those well-defined forms of structures are referred to as organelles. The Endoplasmic reticulum, Mitochondria, and Nucleus are some of the examples of cells’ organelles.
The function and features of the nucleus are listed as follows:
The nucleus is described as the structure that is bounded by the membrane It is also considered the most noticeable organelle based on its function and size This organelle consists of the hereditary information of the particular cell and further helps in controlling the reproduction and growth of the cell.Thus, we can conclude that the statement “contains hereditary information and controls most of the heredity and cell processes” best explains the function of the nucleus.

In chemical reactions atoms are
Neutralized
Destroyed
Created
Rearranged
Answer: Rearranged
Explanation:
In chemical reactions, atoms cannot be destroyed, created, or neutralized, and that is why the only correct answer, in this case, is that atoms in chemical reactions can be rearranged.
They aren't destroyed and they can never be destroyed and also they cannot be created because of the law of conservation of energy in chemical reactions.
This law is considering that ''A matter cannot be created nor destroyed, it can only be formed in one way or the other.''
