Answer:

presence of self replicating molecules

Answer: Paramedics are the medical professionals which perform multitasking in providing medical aid to the patients in the field as well as in the hospital.

Explanation:

Problems encountered by the paramedic at the accidental scene:

1. Major problem is the collection of the blood and other bodily fluids for examination as it is contaminated over spilling on the road.

2. Stabilizing and uplifting of the patient found on accident and curating them to ambulance is a labor consuming task.

3. Some body parts are severely damaged in accidents some of which includes those parts which covers the vital organs like ribs, spinal cord, skull, and pelvis so stabilizing those parts is a risky task for paramedics and can even kill the patient.

Answer:

The circulatory and respiratory systems interact to transport carbon dioxide to the lungs, where it is expelled from the body.

Explanation:

Carbon dioxide produced by the cells and tissues during cellular respiration is removed from the body through the interaction of the circulatory and respiratory system. The medium of transport of carbon dioxide is the blood which carries to the lungs, where it is expelled from the body in ordernto maintain homeostasis in the body.

Carbon dioxide molecules are transported in the blood from body tissues to the lungs in three ways:

1. Dissolution directly into the blood - due to its greater solubility in blood than oxygen, carbon dioxide is dissolved in blood plasma. On reaching the lungs, it leaves the blood by diffusion and is then expelled out of the body.

2. Binding to hemoglobin - carbon dioxide binds reversibly with haemoglobin in the red blood cells to form a molecule called carbaminohemoglobin. When it reaches the lungs, the carbon dioxide freely dissociate from the hemoglobin and is expelled from the body.

3. Carried as a bicarbonate ion - the majority of carbon dioxide molecules are carried as part of the bicarbonate buffer system. In this system, carbon dioxide diffuses into the red blood cells. The enzyme carbonic anhydrase within the red blood cells quickly converts the carbon dioxide into carbonic acid (H2CO3) which then dissociates into bicarbonate and hydrogen ions. The bicarbonate ions leaves the red blood cells in exchange for chloride ions in the plasma. The bicarbonate ions then travel in plasma to the lungs, where they enter the red blood cells again. It combines with hydrogen ions from the haemoglobin to form carbonic acid. Carbonic anhydrase breaks carbonic acid down into water and carbon dioxide which is then expelled from the lungs.

Answer:

Explanation:

This is parenchyma is found below the epidermis of plants and It of living cells that have thin cell walls which are loosely packed to accommodate the intracellular space. Parenchyma consist of chlorophyll and they take part in photosynthesis.

Xylem is called a permanent tissue because it contain various types of cells like tracheids, vessels, xylem fibres, xylem parenchyma which is responsible for storing food.

Answer:

Sickle Cell and Thalassemia are similar because they are both genetic disorders  and are both caused by errors in the genes for hemoglobin, a substance composed of a protein

Explanation:

Answer:

The correct answer is - C. protein.

Explanation:

Ribosomes are biological molecules that are made up of RNA and proteins. These molecules produce protein molecules with the help of mRNA by the process of translation. These molecules are called the factory of protein or protein synthesis site.

The RNA that is present in these molecules is ribosomal RNA. These are attached to the other cell organelles called endoplasmic reticulum used the protein to check and modify them.

Answer:

Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.

Answer: Protists

Explanation:

The protists are organisms which have characteristics similar to both plants and animals. There is huge diversity of protists on earth as they are single celled organisms and they increase in numbers by reproduction. They have a specialized cellular structure which includes organelles like nucleus, mitochondria, and others which are characteristic features of the eukaryotic organisms. They live in moist environment. They engulf their prey this way they are heterotrophic and they can also photosynthesize like plants.

Explanation:

because a vestigal organ is one that serves no relevant purpose and we do not need any of the following options except for the liver.

Explanation:

At least 571 species have been lost since 1750, but likely many more. The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming.

Answer:

Some animals have gone extinct due to over hunting on them for skin, while some have died of because they weren't able to adapt to their environment because it change over time, causing them to go extinct

LAVA FLOWS

Explanation:

Answer:

1. Animals may to environmental stimuli through behaviors that include hibernation, migration, defense, and courtship. As a result of cold, winter weather some animals will hibernate. Examples of hibernating animals maybe ants, snakes, black bears, beavers, and ground squirrels.

2. Plants grow towards the light. Plant leaves bud and seeds germinate when the temperature is right. Their roots and stems grow in certain directions in response to the pull of gravity.

Explanation:

Answer:

a) For example, a cat may see a saucer of milk. Information from

the cat’s eyes travels along nerve cells to the brain, where the brain

processes the information. If the brain decides it wants the milk,

the brain sends a signal to the muscles in the cat’s limbs, and the cat

moves to the saucer of milk and drinks it

Explanation:

b)  For example,

specialized cells in the leaves of trees detect the decrease in sunlight

as winter approaches. Chloroplasts then reduce production of green

chlorophyll. As existing chlorophyll is broken down, other coloured

particles are revealed, creating the beautiful red- and orange-coloured

leaves we see during autumn. Th e leaves eventually die and fall off . In

the spring, increased sunlight and warmer temperatures promote the

production of new leaves containing large amounts of chlorophyll, and

the green colour returns to the leaves.

Answer:

Genetically modified crops (GM crops) are those engineered to introduce a new trait into the species. Purposes of GM crops generally include resistance to certain pests, diseases, or environmental conditions, or resistance to chemical treatments (e.g. resistance to a herbicide).
