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?

Answers

Answer 1

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.

Heart and lungs are the  two organs that are made up of all four tissues.     secretion, movement, strength, excretion and communication are the main functions of tissues.

What are tissues in human body?

Tissues are the same type of group of cells which have the same structure and functions together in a unit. Connective tissue, epithelial tissue, muscular tissue, and nerve tissue are the four fundamental forms of tissue. Other tissues are held together and supported by connective tissue bone, blood, and lymph tissues.

All body surfaces are covered in epithelial tissues, which also line bodily cavities and hollow organs and make up the majority of glandular tissue. Connective tissues are presents in the blood cells in the human body. Loose connective tissue, adipose tissue, dense fibrous connective tissue, elastic connective tissue, cartilage, osseous tissue, and blood are further more tissues in the body.

O They live in the same location.
O They eat different foods.
O They have a wide range of variation

Answers

Finches have adapted different beak sizes and shapes because they eat different foods. So the correct option is C.

What is natural selection?

Natural selection is a mechanism for evolution to happen. It is the process by which living organisms acquire certain characters according to their needs.

It is important to understand natural selection to understand the essential concepts of the processes by which living organisms have been able to develop the complex structures which are helped them to survive.

Natural selection results from various conditions of environment, ecosystem and heredity. An example of natural selection is the development of antimicrobial resistance to pathogens.

Finches are known to have developed different sizes and shapes of beaks according to the kind of food that they eat. If they fed on insects, they had long and pointed beaks. If they fed on seeds and nuts, they had broad and blunt beaks.

Therefore the correct option is B.

which structures in plant cells build protein molecules under the control of the nucleus?
a) cell walls
b) chloroplasts
c)mitochondria
d) ribosomes

Answers

The cell walls, chloroplasts, and mitochondria play important roles in plant cells, they are not directly involved in building protein molecules under the control of the nucleus. D

Ribosomes are the structures in plant cells that build protein molecules under the control of the nucleus.

Ribosomes are tiny, complex molecular machines composed of RNA and protein molecules.

They are involved in the process of protein synthesis, where they facilitate the translation of genetic information from the DNA in the nucleus into functional proteins.

The nucleus of a cell contains the DNA, which serves as the blueprint for building proteins.

However, the actual synthesis of proteins occurs in the cytoplasm, outside the nucleus.

Ribosomes are responsible for this task.

Ribosomes can be found both freely floating in the cytoplasm and attached to the endoplasmic reticulum (ER).

The ones attached to the ER are called rough endoplasmic reticulum (rough ER) due to the presence of ribosomes on their surface.

These ribosomes associated with the rough ER are involved in the synthesis of proteins that are destined for secretion or for integration into the cell membrane.

The process of protein synthesis involves the decoding of the genetic information stored in messenger RNA (mRNA) by ribosomes.

Ribosomes read the mRNA sequence and assemble amino acids into a growing polypeptide chain, forming a functional protein.

Cell walls provide structural support, chloroplasts are responsible for photosynthesis, and mitochondria are involved in cellular respiration. However, the primary site for protein synthesis in plant cells is the ribosomes.

Therefore, the ribosomes (option d) are the structures in plant cells that build protein molecules under the control of the nucleus.

What are Hormones?

Hormones may be defined as chemical substances that are produced by the organ system of an organism and transported at the site of action via the bloodstream. Hormones act as messenger molecules in the body.

Skin acts as the primary or first line of defense for the immune system. It does not secrete any hormones. It plays an important role in innate immunity. Ovaries are responsible for the secretion of hormones like estrogen and progesterone in females and regulate all the prospective consequences in the body of females.

The adrenal gland secretes hormones like cortisol and aldosterone which are steroid hormones. Such hormones are important in regulating metabolism, inflammation, immune functions, etc. The Pancreas secretes insulin and glucagon which play an active role in regulating the level of glucose in the blood.

Therefore, the skin does not secrete hormones. Thus, the correct option is B.

OTwo metals bonded together are going to be more conductive than a metal bonded with a nonmetal.
O The bonds can shift because valence electrons are held loosely and move freely.
O An attraction between a positive charge and a negative charge is created.

Answers

The correct answer is;  Metals have low electronegativity, so they are conductive because they pass charges easily.

Metals are found towards the left hand side in the periodic table. They are known for their low electronegativity. Metals are electropositive. This means that they loose charges(electrons) easily.

A metallic bond is comprised of positively charged metallic ions and a sea of electrons.These electrons can move freely.

This sea of electrons are the charges that are responsible for the properties of metals such as high conductivity.

An antibody molecule has a molecular weight of 150 kD when analyzed by SDS polyacrylamide-gel electrophoresis (SDS-PAGE). Treatment with mercaptoethanol, a reducing agent that breaks disulfide linkages, yields polypeptides with molecular weights of 50 kD and 25 kD, and both of these bands are similar in intensity and thickness. Based on this gel pattern as described, what can we conclude about the molecular composition of the antibody molecule

Answers

Answer:

The antibody has a molecular weight of 150 kD and consists of four subunits: two subunits of 50 kD and two subunits of 25 kD, which are bonded by covalent bonds.

Explanation:

Sodium dodecyl sulfate (SDS) is a detergent used to alter and denature proteins before gel electrophoresis. SDS can break hydrophobic interactions and hydrogen (H) bonds, but this detergent does not break down disulfide bonds, which is a type of covalent bond between two sulfur atoms. Moreover, mercaptoethanol is a reducing agent used to break disulfide bonds. In this case, it is expected that mercaptoethanol can break disulfide bonds between the four subunits of the mature antibody, thereby yielding two bands corresponding to the 50 kD and 25 kD bands (two subunits of 50 kD + two subunits of 25 kD = 150 kD).

Suppose you traveled back in time and located the first animals to have evolved feathers. You found that these animals were tree-dwelling ectotherms, able to run quickly but unable to fly. You also noticed that only males had feathers. Which hypothesis of feather evolution would these data most support? Feathers initially evolved in a role associated with ________.

Answers

Answer:

Feathers initially evolved in a role associated with sexual selection.

Explanation:

In species where only males had feathers, these feathers can be considered to have evolved into a role associated with sexual selection. This is because in these species, males used their feathers as a sexual attraction for females, in this case, females chose the males that had more attractive feathers to mate and generate new individuals for the species. An example of this can be seen in the peacock, where the tail with lush feathers is only present in males and is intended to sexually attract females.

Answers

Answer:

is a thick band of neural fibers enabling communication between the two brain hemispheres.

Explanation:

A brain can be defined as an organ of soft nerve tissue that is found in the skull of vertebrates and it's typically responsible for the coordination of nervous activities, intellect and sensation.

The human brain consists of various sections and these includes;

I. Anterior Cingulate Cortex (ACC) which resembles a bow or collar surrounding the frontal part of the corpus callosum. This is the frontal part of the cingulate cortex which helps to make complex cognitive functions such as impulse control, decision-making, emotions and empathy.

II. Ventral prefrontal cortex in humans are interconnected with the brain and are responsible for the processing of risk, empathy, fear and social decision-making

III. The Cerebral Cortex: this part of the brain primarily comprises of grey matter, foldable sheets of neurons and forms its outermost layer. Therefore, cerebral cortex is known as the outermost layer of the brain (cerebrum) and thus, makes up half of its weight. It is about 2.5 millimeters in thickness and as such it's able to fold.

The corpus callosum is a large, thick band of C-shaped neural fibers found beneath the cerebral cortex and it's saddled with the responsibility of enabling communication between the two brain hemispheres i.e the right hemisphere and the left hemisphere.
