Most of the cells in the human body are diploid.
Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans majority of the cells are diploid and have 23 pairs of chromosomes. The exception are the human sex cells (egg and sperm cells). These contain a single set of chromosomes and are known as haploid.
The amoeba is a eukaryote whose bodies most often consist of a single cell.
The cells of amoebae, like those of other eukaryotes, possess certain characteristic features. For example:-
1. Their cytoplasm and cellular contents are enclosed within a cell membrane.
2. Their DNA is packaged into a central cellular compartment called the nucleus.
3. They contain specialized structures called organelles, which execute a range of cellular functions including energy production and protein transport.
Answer:
Atmospheric carbon dioxide is the raw material for photosynthesis, which plants rely on for producing sugars and other organic compounds.
Explanation:
The most accurate statement that supports the researcher's claim is that atmospheric carbon dioxide is the raw material for photosynthesis.
Photosynthesis is the process by which green plants manufactures their food in the presence of carbon dioxide and water using sunlight.
The product is usually glucose and oxygen.
The chemical equation is shown below;
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
This raw material is a by-product of cellular respiration in human beings. Other process also releases carbon dioxide. Green plants uses this organic material to manufacture its food through photosynthesis.
We can attribute the increased growth rate in plants to the proliferation of the gases in the atmosphere.
Answer: The first three zones of the ocean are called the Intertidal zone, the Neritic zone, and the Open ocean zone.
The open-ocean zone is then split into 3 subzones. These subzones are called; <u>The sunlit zone, twilight zone, and the benthic zone. </u>
The sunlit zone is home to the plankton and jellyfish. The twilight zone is home to the giant squid and deep-sea hatchet fish. The benthic zone has over 200,000 plants and animal species that do not need light to survive.
