2. What are three factors that affect birth and/or death rates?

Answers

Answer 1

Answer:

Political, economic, and religious

Explanation:

Answer 2

Age: Mortality rates are different in different age group. Mortality is high among children and old people but it is low among youths.

Sex/gender: Studies have shown that women have longer life expectancy than men. It may be due to biological and social causes that affectthe life expectancy. Besides, it is also found that death rate among infants is also similar to the life expectancy of adults. The death rates for male infants are higher than those of female infants.

Nutrition Levels: The children, especially under five years of age, die due to lack of nutritious foods. A balanced diet is a must for a healthy living. There are deficiency diseases caused by protein, energy, carbohydrate, malnutrition and also by micro-nutrient deficiencies. These are the causes of high death rates.

Answers

Answer:

Explanation:

Cell Membrane

A thin semipermeable membrane layer of protein and fats surrounding the cell. Its primary role is to protect the cell from its surrounding. Also, it controls the entry and exit of nutrients and other microscopic entities into the cell.

Nuclear Membrane

It is a double-membrane structure that surrounds the nucleus. It is also referred to as the nuclear envelope.

Nucleus

It is an organelle that contains several other sub-organelles such as nucleolus, nucleosomes and chromatins. It also contains DNA and other genetic materials.

Centrosome

It is a small organelle found near to the nucleus which has a thick centre with radiating tubules. The centrosomes are where microtubules are produced.

Lysosome (Cell Vesicles)

They are round organelles surrounded by a membrane and comprising digestive enzymes which help in digestion, excretion and in the cell renewal process.

Cytoplasm

A jelly-like material which contains all the cell organelles, enclosed within the cell membrane. The substance found within the cell nucleus, contained by the nuclear membrane is called the nucleoplasm.

Golgi Apparatus

A flat, smooth layered, sac-like organelle which is located near the nucleus and involved in manufacturing, storing, packing and transporting the particles throughout the cell.

What is mRNA sequence?

The method of choice for evaluating the transcriptomes of disease states, biological processes, and across a wide range of study designs has quickly emerged as mRNA sequencing (mRNA-Seq).

mRNA-Seq can detect both known and novel transcript isoforms, gene fusions, and other properties in addition to being a very sensitive and accurate method of assessing gene expression.

A comprehensive view of the coding transcriptome that is unrestricted by the prior knowledge filter is provided by mRNA-Seq.

what caused a decrease of carbon dioxide in the biodomes air

Answers

Answer:

As organisms release energy during cellular respiration, carbon dioxide is produced from the carbon in energy storage molecules. ... Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall.

There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease like photosynthesis, respiration, ventilation and carbon sequestration.

What are the factors responsible for decrease of carbon dioxide in the biodomes air?

There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease. Some possible causes include:

Photosynthesis: If the biodome contains plants, they may be using carbon dioxide during photosynthesis to produce oxygen and glucose. This process would remove carbon dioxide from the air.

Respiration: If the biodome contains animals or microorganisms that respire, they may be consuming oxygen and producing carbon dioxide. This would result in a decrease in carbon dioxide levels in the air.

Ventilation: If the biodome has a ventilation system, it may be designed to remove excess carbon dioxide from the air. This could result in a decrease in carbon dioxide levels.

Carbon sequestration: If the biodome has systems in place to capture and store carbon dioxide, such as through the use of plants or other methods, this could result in a decrease in carbon dioxide levels in the air.

It's important to note that the specific cause of a decrease in carbon dioxide levels in the biodome's air will depend on the specific conditions and systems in place within the biodome.

Achromoplast stores while a leucoplast stores A. starch; pigments B. chlorophyll; starch C. pigments; chlorophyll D. pigments; starch​

Answers

Answer:

D. pigments; starch.

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.

In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.

A chromoplast can be defined as a heterogeneous organelle or plastids that is typically responsible for pigment synthesis and their storage in a plant. The pigments include red, orange, yellow or chlorophyll.

On the other hand, leucoplast is a colorless plastid i.e plastic lacking photosynthetic pigments that are typically found in storage organs, underground stems, cotelydons, roots, tubers, seeds, or endosperm etc., used for the storage of starch in the absence of sunlight.

Hence, a chromoplast stores pigments while a leucoplast stores starch.

A. Sickle Cell Anemia is caused by a base change in DNA. Describe how the base change results in a faulty protein being made.

B. Briefly explain the inheritance pattern of the condition.

Answers

Answer: a) The single base change mutation occurs at the beta chain of haemoglobin when glutamic acid is replaced with valine.

b) Sickle Cell Anemia is inherited in an autosomal recessive pattern.

Explanation:

Haemoglobin is a protein found in the red blood cells whose main function is to transport oxygen. Sickle Cell Anemia is a disorder caused by a base change in DNA beta chain of haemoglobin. The amino acid valine is substituted for glutamic acid at one point in each of the two beta chains. When this type of hemoglobin is exposed to low oxygen, it forms elongated crystals inside the red blood cells that are sometimes 15 micrometers in length. These make it almost impossible for the cell to pass through many small capillaries, and the spiked ends of the crystals are likely to rupture the cell membrane, leading to sickle cell anemia.

In describing the inheritance patterns of sickle cell anaemia, it is of autosomal recessive pattern. This means that the parent of the affected individual both carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. The gene for normal red blood cell is dominant over the gene for abnormal red blood cell which is said to be recessive. A person who is a stickler should have the genotype SS.
