Well this isn’t biology this is earth science but it doesn’t have the option.... 1. What geologic processes must have occurred for fossil ammonites (relatives to the nautilus that dominated oceans hundreds of years ago) to now be found in rocks at the highest mountains on Earth??
2. What would our planet look like if it contained no radioactive isotopes within it? What would it look like if radioactivity were producing twice as much heat within Earth’s interior?
The answers are that the geological process responsible for fossils being found on high mountains today is called Orogeny Tectonics. With no radioactive isotopes, the Earth's geography would be vastly different and void of life. If radioactivity produced twice as much heat the earth would become unstable.
The discovery of fossil ammonites within rocks at the highest mountains on Earth is due to orogenic plate tectonics. Plate tectonics is the name we use to describe a process in which pieces of the earth's crust move and often slam into each other, causing one of these to pile onto the other.
This can lead to the formation of mountains and mountain ranges. This process helps to explain why fossils of ammonites known to dwell in the ocean can be found in mountains.
Radioactive isotopes, or better yet, the decaying of radioactive isotopes, are responsible for generating most of the Earth's internal heat. The internal heat of the earth is the driving force of plate tectonics and without it, much of the geological activities responsible for the earth's current geography would not have happened.
Mountain ranges would not have formedPlate tectonics would not have caused the formation of the continents we know todayThe earth would lack a magnetic field to defend against ionizing radiation from the sunLife would likely not have evolved.Radioactive isotopes were vital in allowing for the conditions of the earth at the time that life evolved, and the heat they produce allows the earth to have a molten core and thus generate a magnetic field for protection.
Now, if the heat produced by radioactive isotopes were to double, the Earth's internal temperature would nearly double. Since this heat is the driving force for plate tectonics, we can expect a sharp increase in the number of earthquakes and volcanic eruptions. These can, in turn, cause tsunamis and changes to the earth's global temperature. Mountains would form continuously and continents may break apart. This instability would make life on earth's surface improbable.
Therefore, the geological process responsible for fossils being found on high mountains today is called Orogeny Tectonics. Without radioactive isotopes, the Earth's geography would be vastly different and void of life. Radioactivity producing twice as much heat would make the earth very unstable.

describe the role of enzymes in seeds germination
Answer:
Enzymes such as amylase ,protease and lipase are liable for solubilizing spare food materials in form of starch, protein and lipids correspondingly
in seed and deliver energy and other fundamentals food materials to germinating embryo.
The seed proteins are catalyzed by protease enzyme and break it into amino acid and peptides that a e transferred to growing embryo.
The amino acids obtained from metabolism of the proteins are further used in biosynthesis of enzymes,hormones,proteins, pyrimidines and Purine bases.
The starch is catalyzed by enzyme amylase that provides the food materials for growth and development of embryo . Similarly lipase are enzymes that are responsible for metabolism of the triacylglycerols into glycerols and fatty acids.This is also the source of energy for growing embryo

22. An astronaut on the space station tests whether gravity affects the productivity of tomato plants. What
is the independent variable in this experiment?
When conducting an experiment, the independent variable is always the one that produces or causes an effect or reaction on the dependent variable. In the exposed situation, the independent variable is gravity.
--------------------------------------
During an experiment, you need to consider all the variables involved.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified to analyze how another variable responds to it. The researcher changes the independent variable to observe its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, gravity is the independent variable, and influences the productivity of tomato plants. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. Controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.------------------------

Genetic variation is more commonly found in sexually reproducing organisms, as compared to asexually reproducing organisms, because
1 point
in asexual reproduction gametes fuse to lead to new genetic combinations
in sexual reproduction the gametes formed are all genetically identical
in asexual reproduction the gametes formed are genetically different
in sexual reproduction gametes fuse to lead to new genetic combinations
Answer:
In sexual reproduction gametes fuse to lead to new genetic combinations
Explanation:
In sexually reproducing organisms, there are two parents who create genetically diverse offspring.
This occurs because the gametes of the two parents combine to create very unique genetic combinations, which lead to increased genetic variation.
On the other hand, asexually reproducing organisms reproduce without a partner.
Their offspring are identical clones to the parent, so they have much less genetic variation.
So, the correct answer is that In sexual reproduction gametes fuse to lead to new genetic combinations.

Haploid+ Haploid = Diploid represents fertilization. So, the correct option is (C).
What is Fertilization?
Fertilization is defined as the process in which two gametes where one male and one female first form a zygote and then lead to the development of an embryo.
These germ cells are cells that give rise to gametes – either egg cells that are female gametes or sperm cells that are male gametes.
These germ cells are the only cells that can undergo both mitosis and meiosis. These are the diploid cells present in the gonads. After meiosis, haploid gametes are produced. In fertilization two haploid gametes fuse (n+n) and form a diploid zygote (2n)

The operation of the sodium-potassium pump moves ________. A) sodium and potassium ions into the cell B) sodium and potassium ions out of the cell C) sodium ions into the cell and potassium ions out of the cell D) sodium ions out of the cell and potassium ions into the cell
operation of SODIUM-POTASSIUM PUMP moves sodium ions out of the cell and potassium ions into the cell. The correct option is D.
When a cell membrane moves molecules or ions against a concentration gradient or against an electrical or pressure gradient, the process is called ACTIVE TRANSPORT. Different substances that are actively transported include:
--> sodium ions,
--> potassium ions,
--> calcium ions and
--> some amino acids.
There are two types of active transport which are divided according to the energy that is used to cause the transport. They include:
--> primary and
--> secondary active transport.
PRIMARY ACTIVE TRANSPORT
A typical example is the SODIUM-POTASSIUM PUMP( Na+ - k+). This is a transport process that pumps sodium ions outward through the cell membrane of all cells and at the same time pumps potassium ions from the outside to the inside. This pump helps to:
--> maintain the sodium and potassium concentration differences across the cell membrane
--> establish a negative electrical voltage inside the cells.
The mechanism or OPERATION of the pump involves the following steps:
--> two potassium ions bind on the outside of the carrier protein and three sodium ions bind on the inside,
--> ATpase of the carrier protein cleaves one molecule of ATP, splitting it to Adenosine diphosphate (ADP) and liberating a high-energy phosphate bond of energy.
--> this liberated energy then causes a chemical and conformational change in the carrier protein,
-->this leads to the extruding of three sodium ions (3Na+) to the outside and two potassium ions (2K+) to the inside.
Therefore in the operation of SODIUM-POTASSIUM PUMP moves sodium ions out of the cell and potassium ions into the cell. The correct option is D.
