Harry is doing a research project on the movement of plants from the ocean to land. He leaned that plants evolved
vascular tissues, which enabled them to pull water from the ground and survive on land. Which is most likely
another adaptation that contributed to the success of land plants?
cell walls?
chloroplasts
waxy cuticle
gametes
Answer:
Waxy Cuticle
Explanation:
Waxy Cuticle retains water. It's the closest in terms of surviving on land. For instance, the plants living in water do not need waxy Cuticle to retain or maintain water. The plants on land requires waxy Cuticle because the temperature is hotter than in the water and they are at higher risk of loosing water during hot seasons and climate. waxy Cuticle aids in their water retention allowing them to adapt to live on land.

In the plasma membrane, the phospholipid heads Group of answer choices are isotonic and do not respond to water. are hydrophobic and face inward, shielded from water. are hydrophilic and face inward, shielded from water. are hydrophilic and face outward toward the aqueous solution on both sides of the membrane. are hydrophobic and face outward toward the aqueous solution on both sides of the membrane.
Answer:
hydrophilic and face outward toward the aqueous solution on both sides of the membrane
Explanation:
The cell membrane is mainly composed of phospholipids, which are arranged in a lipid bilayer. In general, phospholipids consist of a glycerol unit, a phosphate group, and two fatty acids. In a lipid bilayer, hydrophilic (polar) phosphate heads are always oriented outwards and interact with surrounding water molecules; whereas hydrophobic fatty acid tails are oriented towards the center of the lipid bilayer away from water. It is for that reason that phospholipids are considered to be amphipathic molecules, where fatty acids confer hydrophobic properties and polar phosphate groups confer hydrophilic properties.

This organ stores the main metal ion that forms part
of the red blood cell. Which ion is this, and what
molecule is it a part of inside the red blood cell?
Answer:
a. Iron (Fe) ion
b. Haemoglobin
Explanation:
Red blood cells (RBC), also known as erythrocytes, are one of the cells found in the blood. Red blood cells are the major components of the blood involved with the transport of oxygen throughout the body. Red blood cells are able to do this because they contain proteinous molecules called HAEMOGLOBIN.
Haemoglobin is a molecule that contains hemic iron groups. Haemoglobin is composed of an IRON ION at the core of its structure, which binds to oxygen atom. Hence, according to this question, haemoglobin is a proteinous molecule that contains iron-binding heme groups in the red blood cells.

What kind of question would an ancient myth try to answer?
How are the moon and the tides connected?
What minerals cover the surface of the moon?
Which phase of the moon is most beautiful?
Why does the moon get smaller and disappear?
Answer:
why does the moon get smaller and dissapear?"
Explanation:
One of the questions that ancient mythology would try to answer would be "why does the moon get smaller and dissapear?" Ancient mythology stories always try to explain everyday occurrences in individuals lives that did not really have a simple explanation at the time due to lack of knowledge. Therefore, these stories usually involved the acts of deities to explain the different unknown events in the world such as the moon dissapearing, shooting stars, volcanoes, hurricanes, etc.
The evolutionary history and development of whales has been hotly debated. Recently there has been a major shift in our understanding of the processes used to detail whale evolution. This indicates that: Group of answer choices A) Aspects of evolution are constantly being challenged and explored in light of new evidence. B) Gaps in the fossil records will never allow us to fully understand evolution. C) Scientists studying evolution typically present ideas with very little evidence, leaving it to others to find proof of their ideas. D) Much of the science of evolution is based on speculation that can easily be changed when scientists think of new ideas.
Answer:
Aspects of evolution are constantly being challenged and explored in light of new evidence
Explanation:
The whole idea of evolution has to do with the fact that organisms developed into their present form from simpler life forms. According to Oxford dictionary, evolution is; ''the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth.''
Evolution depends on evidence from fossil records. Evidences that support the theory of evolution continue to be amassed as science advances. Hence, aspects of evolution are constantly being challenged and explored in light of new evidence.
For this reason, the evolutionary history and development of whales is being hotly debated and there has recently been a major shift in our understanding of the processes used to detail whale evolution.

Why do cells use fat and starch for long-term energy storage instead of ATP molecules?
O ATP is used for long-term storage, while fat and starch are used for immediate energy.
O ATP is used for short-term energy and to build molecules of starch and fat.
O Fat and starch are unstable and can be stored short-term, while ATP molecules are stable and stored long-term.
O Fat and starch are stable if used as energy immediately, while ATP is used as long-term storage.
Answer:
Cells use fat and starch for long-term energy storage instead of ATP molecules because fat and starch are more efficient energy storage molecules than ATP.ATP is a molecule used for immediate energy, not for long-term energy storage.
Fat and starch are complex carbohydrates that can be broken down to release energy. Fat molecules are primarily composed of carbon and hydrogen, while starch is made of glucose molecules.Both fat and starch can be broken down through cellular respiration to produce ATP molecules that can be used to power various cellular processes.
However, because fat and starch molecules contain more chemical energy than ATP, they can provide a much larger amount of energy over a longer period of time.
Furthermore, ATP molecules are relatively unstable and cannot be stored for long periods of time, while fat and starch can be stored in specialized cellular structures for long-term energy needs.

Explica brevemente en que consiste la teoría de la deriva continental y menciona los contenientes que se crearon a partir de la Pangea
Esta teoría hace referencia al movimiento actual de las placas que sustentan los continentes y que se desplazan a lo largo de millones de años. En toda la historia geológica de la Tierra, los continentes no han estado siempre en la misma posición. Existe una serie de evidencias que veremos posteriormente que ayudaron a Wegener a refutar su teoría. El movimiento se debe a que continuamente está formándose nuevo material procedente del manto. Este material se crea en la corteza oceánica
As more is learned about cancer, it has become clear that cancer, with few exceptions, ________. Group of answer choices is only dependent on the inherited genetics is a result of genetics and environmental factors is 100% dependent on inherited genetics has no genetic basis
Answer: Is a result of genetics and environmental factors.
Explanation:
Cancer is the common name for a group of diseases in which there is a division of the body's cells, whose growth exceeds that of normal tissues and which persists in the same excessive manner. It can begin in a localized manner and spread to other surrounding tissues and its malignancy is very variable, according to the aggressiveness of its cells and other biological characteristics of each type of tumor. In general, the behavior of cancer cells is characterized by lacking the reproductive control required by their original function, acquiring the capacity to invade tissues (metastasis), spreading through the organism via the lymphatic or circulatory system, and causing the growth of new tumors in other parts of the body.
A gene is a hereditary unit composed of DNA that carries the instructions for producing proteins, which do much of the work in our cells. Certain genetic alterations can cause cells to evade growth controls and become cancerous cells. These changes can be inherited from our parents if the changes are present in the germ cells (eggs and sperm) and they are called germline changes. In addition, cancer-causing genetic changes can also be acquired during a person's lifetime (somatic or acquired changes), as a result of DNA errors that occur when cells divide either spontaneously or by exposure to carcinogenic substances that damage DNA (environmental factors), such as certain chemicals in tobacco smoke, or radiation, such as ultraviolet rays from the sun. These substances damage DNA, acting as mutagens.
Sometimes, the changes are not in the DNA sequence. For example, the epigenetic modifications are the presence of chemical marks in DNA which can determine if the gene is expressed. This means, whether and how much messenger RNA is produced, because the messenger RNA is translated into proteins.
So, cancer cells have genetic changes compared to normal cells. These changes are due to mutations that can be inherited, acquired spontaneously during life, or acquired due to environmental factors such as sun exposure, smoking, and other factors. In addition, the fact that a person has the cancer-related mutation does not necessarily mean that he or she will develop the disease during his or her lifetime. In some cases, even if they have this genetic vulnerability, they remain healthy, because cancer is a multifactorial disease that depends on many factors, such as the immune system, nutrition and certainly many others currently unknown to medicine.

what is the prediction of the outcome.genetic crosses between various organisms
Answer:
The results of genetic crosses can be predicted using a chart called a Punnett square. In a Punnett square, the possible male and female gametes of each parent are written across the side and top of the square. The interior squares represent every possible combination of gametes that could combine to form a zygote.
Explanation:
To fill in the square, look at the alleles of the games on the outside edges and bring them across and down to fill in the center of the square. If the offspring is heterozygous, we will write the capital letter in front of the lower case letter.

What's photosynthesis?[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Photosynthesis is the process in which green plants derive their food (nutrients and water) through the capturing of light energy (sunlight) and using it to convert carbon dioxide (CO2) and water (H2O) into oxygen (O2) and other substances (compounds) that are rich in energy. Chlorophyll a green pigment present in plants is used in this process.

What type of organisms make up the majority of life on the surface of the pelagic zone?
chemosynthetic bacteria and invertebrates
seaweed and fish
mollusks and seaweed
plankton and algae
The types of organisms that make up the majority of life on the surface of the pelagic zone are plankton and algae. That is the last option, as plankton and algae are the primary producers in the surface layer of the pelagic zone.
What are the zones of water?
The pelagic zone is the open ocean area that comprises the largest ecosystem on Earth. It is divided into different layers depending on the depth and amount of sunlight that penetrates the water. The surface layer of the pelagic zone, also known as the photic zone, is the layer that receives enough sunlight for photosynthesis to occur, and it is where most of the ocean's primary production takes place.
Hence, the types of organisms that make up the majority of life on the surface of the pelagic zone are plankton and algae, which is the last option.
