why is it necessary for scientists to use clues from celestial objects to determine the age of our planet?
Answer:
Meteorites, which are the very components of our planets (through the process of accretion), are the remnants of the Solar System's origins. Dating meteorites thus allows us to give a lower age to the Solar System (4,56 billion years old).

For many generations, the flowers in a meadow have been pollinated by a particular species of honeybee. One year, a new species of
honeybee moves to the meadow. This new species pollinates the same flowers as the old species. Which description best predicts
what would happen if a new species of honeybee moves into a meadow that was already occupied by a particular honeybee that
pollinated the meadow?
Answer:
By the process of mating there will be again undesirable species (hybird) and the particular honey bee might get extinct.
There will be imbalance in ecosystem if a new species of honey bees moves into a meadow that was already occupied by a particular homey bees.

Explanation: Translation has pretty much the same three parts, but they have fancier names: initiation, elongation, and termination. Initiation ("beginning"): in this stage, the ribosome gets together with the mRNA and the first tRNA so translation can begin.

why does max scherzer have two different colored eyes?
Answer:
he has heterochromia iridis
Explanation:
Scherzer has an uncommon condition called heterochromia iridis that affects less than 200,000 people in the United States. The condition, which in most cases doesn't damage the eyes, is caused by the distribution and levels of melanin in the irises
Please help with answer 3 :)
Answer:
1) Diffusion : Is the movement of molecules / ions from a region of higher to lower concentration. It may or may not occur across a semi permeable membrane.
In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.
2) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. Here metabolic energy ATP is required.
3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport.
Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.
4) Osmosis : is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane.
The cell membrane being permeable to water allows to and fro movement of water molecules along the concentration gradient.
Which of the following correctly describes how the chemical equation for cellular respiration would differ from a chemical equation for photosynthesis?
Answer:
Uh not seeing an option but I hope this helps
The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.

Explanation:
what would happen to you metabolically if all your mitochondria were destroyed
Answer:
You would die
Explanation:
if you lost your mitochondria you would die
The loss of functional mitochondria would result in a severe energy crisis within the cell, affecting ATP production and impairing Fatty acid metabolism and calcium homeostasis.
Mitochondria are known as the "powerhouses" of the cell because they are responsible for producing most of the cell's adenosine triphosphate (ATP).
The following processes would be affected:
1. ATP production: Without functional mitochondria, ATP production would be significantly reduced, leading to a severe energy deficit within the cell.
2. Oxidative phosphorylation: Mitochondria are crucial for oxidative phosphorylation, a process that occurs in the inner mitochondrial membrane and generates a large amount of ATP. Without intact mitochondria, oxidative phosphorylation would be disrupted, impairing ATP synthesis.
3. Metabolism of fatty acids: Mitochondria are involved in the breakdown of fatty acids through a process called beta-oxidation. If mitochondria were destroyed, the ability to efficiently metabolize fatty acids would be compromised.
4. Reactive oxygen species (ROS) regulation: If mitochondria were destroyed, the regulation of ROS levels would be impaired, potentially leading to oxidative damage and disruption of cellular processes.
5. Calcium homeostasis: Mitochondria are involved in maintaining calcium homeostasis within cells. Loss of functional mitochondria would disrupt calcium regulation, which could affect various cellular functions, including muscle contraction, enzyme activity, and cell signaling.
Therefore, the loss of functional mitochondria would result in a severe energy crisis within the cell, affecting ATP production and impairing various metabolic processes.

Which of the following statements is true?
Answer:
The First one, second and forth are false
and the 3 one is true
Explanation:
The DNA is doble stranded in a double helix structure. There are 5 nucleobases (adenine (A), cytosine (C), guanine (G), thymine (T), and uracil(U)), only the first 4 are present in the DNA whilist the U substitutes the T in RNA.
The DNA has deoxyribose sugar while RNA has ribose sugar, that's what gives the doble stranded and single stranded form respectively.

Explanation:
The function of the mitotic cell cycle is to produce daughter cells that __________.
a. have the same number of chromosomes as the parent cell but not the same genetic content.
b. have the same number of chromatids as the parent cell had chromosomes.
c. have a random assortment of maternal and paternal chromosomes.
d. are genetically identical to the parent cell (assuming no mutation has occurred).
e. have none of the listed characteristics.
Answer:
The answer is D.are genetically identical to the parent cell (assuming no mutation has occurred).
Explanation:
The function of the mitotic cell cycle is to produce daughter cells that __________.
the division results in the generation of two daughter cells that are genetically identical to the parent cells and each daughter cell contains the same number of chromosomes and all cell content inherited from the parent cell.

Does gypsum occur naturally pls give an explanation
Answer:
its a naturally occurring mineral
Explanation:
Gypsum is made up of oxygen, sulfur, calcium and water. As evaporation occurs the sulfur is not protected by the water and oxygen contacts sulfur bonding with it to form a sulfate. The sulfate then bonds with calcium and water to create gypsum.

Explain how the model of the chemical reaction above demonstrates that matter is conserved.
Answer:
Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions

What is recombinant DNA ?
Recombinant DNA are the molecule which has been modified to include genes from different origin by the process of either genetic recombination or through laboratory techniques.
In the lab condition, bacteria can be transformed with recombinant DNA and Genetic recombination occurs via crossing over.
scientists use this recombinant DNA technology created to add to the genome of another organism which means that scientists can easily add genes from one species into bacteria for the production of the product.
For example, insulin is produced by recombinant DNA technology within bacteria where human insulin gene is inserted into a plasmid, then introduced to a bacterial cell, followed by the production of insulin by bacteria cell.

Help you later
Ozone levels in 1920 were primarily monitored using chemical methods, such as the use of chemical indicators and colorimetric analysis.
Potassium iodide-starch paper was used to detect ozone. When exposed to ozone, these indicators changed colour, letting researchers visually monitor ozone concentration.
Colorimetric analysis was also used. Chemical reagents reacting with ozone changed colour. Ozone concentration connected with colour change intensity. Chemical approaches measured ozone qualitatively or semi-quantitatively. They were easy to use but less precise than modern monitoring approaches.
In the following decades, spectrophotometry and ozone analyzers improved the systematic monitoring and quantitative measurement of ozone levels. These improvements made atmospheric ozone monitoring more precise.
