What are the three types of RNA and how does each contribute to protein synthesis?
There are 3 types of RNA:
mRNA (Messenger RNA): This RNA is in charge to travel the genetic information from the nucleous to the ribosome, where it binds to it and give the genetic instructions for protein synthesis.
tRNA (Transfer RNA): This RNA is in charge of providing the correct amino acid to the ribosome during protein translation.
rRNA (Ribosomal RNA): This RNA are structural proteins of the ribosomes.
how does the ocean remove carbon dioxide from earth's atmosphere? what role do tiny marine organisms, such as foraminifera, play in the removal of carbon dioxide?
The ocean plays a significant role in removing carbon dioxide from the Earth's atmosphere. It absorbs about 25% of the carbon dioxide that is emitted by human activities every year.
When carbon dioxide dissolves in seawater, it forms carbonic acid, which then dissociates into hydrogen ions and bicarbonate ions. These ions can then react with other dissolved substances, forming calcium carbonate. Calcium carbonate is the primary building block for the shells and skeletons of many marine organisms, including foraminifera.
Foraminifera are tiny marine organisms that secrete a calcium carbonate shell or test. They are particularly important in the ocean's carbon cycle as they incorporate carbon into their shells as they grow. When foraminifera die, their shells sink to the seafloor, where they can become buried and sequestered for millions of years, effectively removing carbon from the atmosphere. In this way, foraminifera and other marine organisms play a crucial role in the removal of carbon dioxide from the atmosphere and the storage of carbon in the ocean.

according to biological theories, the basic determinants of human behavior may be inherited. select one: true false
The given statement," According to biological theories, the basic determinants of human behavior may be inherited," is True because according to biological theories, human behavior may be influenced by inherited factors such as genetics, hormonal imbalances, and brain chemistry.
This perspective, often referred to as biopsychology or behavioral neuroscience, suggests that the biology of the brain and nervous system underlies all behavior, including human behavior. This includes the genetic and neurological factors that contribute to the development of individual differences in temperament, personality, and other psychological traits that shape behavior. However, it is important to note that biological factors are not the only determinants of behavior, as environmental and social factors also play a role

Write an expository essay explaining how the ideas of cell theory, heredity and genetics, and
evolation through natural selection are used by biologists to explain the unity and diversity of
life on earth today
Unity in diversity is best explained by the collaboration of research works by scientists, with the help of cell theories and genetics and natural selection.
What is evolution and how come unity in diversity can be explained?Evolution is the gradual change in the evolving of different species on Earth so far from simple to complex phenomena. Natural selection was discovered by Darwin and was first invented in the land of flinches, with the alteration in the beaks. Genetics is always remembered by Mendel's experiment initially and contributed largely to the evolution of species. Unity in diversity is the collaborative invention of all the researchers that got in the way of inventing natural selection to the cell theory. Biologists explain that this vast diversity on our planet is all safe and together due to unity.

Which of the following is not recycled in the ecosystem? A. Nitrogen B. Water C. Energy D. Oxygen
The correct answer is C. Energy.
In an ecosystem, matter and nutrients are recycled through various biogeochemical cycles, ensuring the availability and sustainability of essential elements. However, energy is not recycled in the same way as matter.
Energy flows through an ecosystem in a one-way direction. It enters the ecosystem from an external source, typically the Sun, and is captured by autotrophic organisms (such as plants) through photosynthesis. This captured energy is then transferred to heterotrophic organisms (such as animals) through food chains and food webs.
As energy flows through the ecosystem, it is continuously used and transformed by organisms for various metabolic processes, such as growth, movement, and reproduction. However, it is not recycled back into the ecosystem once it is used. Instead, it is dissipated as heat energy and lost from the ecosystem.
In contrast, the other options mentioned are actively recycled in the ecosystem:
A. Nitrogen: Nitrogen is an essential nutrient that cycles through the nitrogen cycle. It is taken up by plants from the soil, passed on to animals through consumption, and returned to the ecosystem through processes like decomposition and nitrogen fixation.
B. Water: Water is continuously recycled in the hydrological cycle. It evaporates from water bodies, condenses to form clouds, falls as precipitation, and returns to water bodies through runoff or infiltration.
D. Oxygen: Oxygen is produced by photosynthetic organisms during photosynthesis and is consumed by organisms during respiration. It is continuously cycled between the atmosphere, plants, and animals.
Therefore, while matter and nutrients such as nitrogen, water, and oxygen are actively recycled in the ecosystem, energy is not recycled and is instead lost as heat energy.

Explanation:
In question 1 ;
The independent variable is the fertilizer
The dependent variable should be the rate of growth of the plants
The constant doesn't change so other factors that affect plant growth and health, such as soil quality and watering, would need to remain constant.
The controlled variables might be things such as the the quality of soil and the amount of water given to the plants. If these factors were not constant, and certain plants received more water or better soil than others
The experiment in question 1 is a controlled experiment
The part of the garden that didn't receive fertilizer is the control group
According to the question; She didn't hypothesize .
In question 2 '
The independent variable is the floor wax
The dependent variable was protecting the floor tiles against scratches.
It is a controlled experiment but there's no much information to determine if there is any variability and repetition )
The sections that received no wax is the control group
There is no hypothization (if that's a word :) ).The shopping mall didn't hypothesize (maybe that the tough steel would be better )
I'm not sure of any constant needed when applying floor wax.
The figure shows a phylogenetic tree of various members of the order Proboscidea, which includes modernelephants. Which of the following claims is best supported by the information in the figure ?(A)The Asian and African elephants are the most closely related species shown on the tree.(B)The mammoth diverged from its most recent common ancestor with African elephants before themastodon diverged from its most recent common ancestor with Stegodons.(C)The mastodon and the Stegodon diverged from their common ancestormillion years ago.(D)The common ancestor of the African elephant and the mastodon is the Palaeomastodon.
The claim best supported by the information is (B) The mammoth diverged from its most recent common ancestor with African elephants before the mastodon diverged from its most recent common ancestor with Stegodons.
Did the mammoth diverge from its common ancestor with African elephants before the mastodon diverged from its common ancestor with Stegodons?The phylogenetic tree provides information about the evolutionary relationships among various members of the order Proboscides, including modern elephants. Based on the tree, the claim best supported is (B) The mammoth diverged from its most recent common ancestor with African elephants before the mastodon diverged from its most recent common ancestor with Stegodons.
By examining the branching patterns on the tree, we can see that the branch leading to the mammoth separates from the branch of African elephants before the branch of the mastodon separates from the branch of Stegodons. This indicates that the divergence between the mammoth and African elephants predates the divergence between the mastodon and Stegodons.
It's important to note that the tree does not provide specific time estimates for the divergences or the age of the common ancestor. It only shows the relative order of branching events. To further investigate the timing and details of these evolutionary relationships, additional research and evidence would be necessary.

In science, models can show a process that’s difficult to observe directly. Using the style of the model shown, draw the process that describes the rest of the steps in protein synthesis.
The model is in the annex.
The model below states that following the transition, the RNA is in a form known as pre-mRNA where exons and introns may be seen. Splicing is a procedure used to eliminate introns from the RNA molecule since they are not nitrogenous base sequences that can contribute to the creation of proteins. When the introns have been eliminated, the mRNA is prepared for exportation, which involves moving it from the nucleus to the cytoplasm. When the mRNA reaches the cytoplasm, it works with the tRNA, ribosomes, and other molecules to produce a polypeptide chain through a process known as translation, which converts nitrogenous bases into amino acids.The amino acids of the polypeptide chain are arranged in a straight line.
