1. Mistletoe is parasitic to the mesquite tree, it steals from the tree without giving anything valuable back to it. In this case, only the mistletoe gains an advantage.

2. If the mistletoe population on the tree were to increase, the mistletoe would probably end up slowly killing the tree. I say this because its a parasite to the tree. Its constantly stealing water and valuable minerals that it needs and doesnt give back anything that could help the tree. With all the water and minerals being stolen and an uneven rate with no way for the tree to replenish it all quickly enough it'll die.

3. Its parasitic since the mistletoe just takes and takes harmfully  

Mistletoe plant is a parasite on the mesquite tree as it takes all the valuable minerals and water from the plant and does not give anything valuable in return to the mesquite tree.

A food web is a network of interconnected food chains that shows the flow of energy between different organisms.

A food web is a graphical representation of the interrelated feeding relationships among organisms in a particular ecosystem. It shows the transfer of energy and nutrients from one organism to another through predation, parasitism, and other forms of feeding interactions. In a food web, each organism is classified as a producer, consumer, or decomposer based on its role in the ecosystem. Producers, such as plants, use photosynthesis to create their own food.

Primary consumers, such as herbivores, eat producers, while secondary consumers, such as carnivores, eat primary consumers. Decomposers, such as fungi and bacteria, break down dead organic matter and recycle nutrients back into the ecosystem. The food web helps to illustrate the complex and interconnected relationships that exist in an ecosystem, emphasizing the importance of preserving biodiversity and maintaining a balanced ecosystem.

In the small intestine, parasympathetic correct impulses stimulate peristaltic movements, while sympathetic correct impulses inhibit movements.

The small intestine is a long, narrow tube that is part of the digestive system. It is responsible for the majority of nutrient absorption and plays a critical role in the digestion of food. Peristalsis is the process by which food is moved through the digestive tract via a series of contractions and relaxations of the smooth muscle in the intestinal wall. The rate and intensity of peristalsis is controlled by the autonomic nervous system.

The parasympathetic nervous system is responsible for stimulating digestive activity, including peristaltic movements in the small intestine. When food is detected in the small intestine, sensory neurons send signals to the brain, which then sends signals back down the vagus nerve to stimulate the release of acetylcholine.

Answer:

The correct answer is - Fossil fuels are cheaper than alternative forms of energy.

Explanation:

Fossil fuels are made by the natural process in a longer time period such as anaerobic decomposition of the dead organism like plants, and animals. These plants and animal's decomposed organic matter pilled up to form coal, or natural gases or crude oil.

By the use of such fuels the reserves are continuously depleting and will be no longer available in the future if not managed properly as it can not be renewed. Fossil fuels increases the green house gases in environment and affect it by incresing carbon in atmosphere. However, these fuels are cheaper in comparision of other fuels.

Thus, the correct answer is - Fossil fuels are cheaper than alternative forms of energy.

The triiodothyronine absorption through different tissues lead to different signal transduction pathways.

The deuterostome group's gene arrangement in the mitochondrial genome of Xenoturbella bocki is remarkably close to that of the chordates and hemichordates and hence to the ancestor deuterostome gene order. Inversion and breakpoint studies particularly point to a similarity to the hemichordates.

Previous morphological investigations imply that Xenoturbella could be classified as a bivalve mollusc, a basal bilaterian, a turbellarian flatworm, a sister group to the echinoderms(nonvertebrate), or a hemichordate. Recent genetic analyses that focus mostly on nuclear genes appear to favour the Ambulacraria (echinoderms + hemichordates). In contrast, a basal deuterostome location is supported by mitochondrial sequences.

A reflex is electrical communication between neurons (Option A).

A reflex is an automatic motor response that is usually triggered by a stimulus. Reflex happens rapidly and is completed without the brain's conscious control. A reflex involves electrical and chemical communication between neurons, but it is not preplanned.

A reflex is an involuntary reaction that occurs when the body encounters a stimulus. It is a specific type of response to stimuli that does not require conscious thought.

Therefore, an automatic motor response is the best definition of a reflex. For example, if you accidentally touch a hot stove, your hand automatically and quickly pulls away from the heat. This automatic reaction occurs without thinking about it.

Thus, the correct option is A.

Respiration and fermentation are two different metabolic processes used by living organisms to generate energy.

Respiration involves the use of oxygen and the breakdown of glucose to produce ATP, while fermentation involves the breakdown of glucose without oxygen to produce ATP.

Advantages of respiration over fermentation include: 1. Higher energy yield: Respiration produces a higher amount of ATP compared to fermentation, making it a more efficient process for energy production.

2. Aerobic endurance: Respiration allows for sustained energy production during aerobic endurance activities such as long distance running or cycling.

3. Efficient removal of waste products: Respiration produces carbon dioxide and water, which are easily eliminated by the body as waste products.

Disadvantages of respiration over fermentation include: 1. Dependence on oxygen: Respiration requires the presence of oxygen, and therefore cannot be sustained under anaerobic conditions.

2. Slower process: Respiration is a slower process compared to fermentation, as it involves several enzymatic reactions.

Advantages of fermentation over respiration include: 1. No need for oxygen: Fermentation can occur in the absence of oxygen, making it a useful process for organisms living in anaerobic environments.

2. Faster process: Fermentation is a faster process compared to respiration, as it involves fewer enzymatic reactions.

Disadvantages of fermentation over respiration include: 1. Lower energy yield: Fermentation produces a lower amount of ATP compared to respiration, making it a less efficient process for energy production.

2. Build-up of waste products: Fermentation produces lactic acid and other waste products, which can build up in the body and cause fatigue or muscle soreness.

Answer: Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.This energy makes carbon molecules an excellent source of fuel for all living things. During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel glucose and other sugars for building plant structures. This process forms the foundation of the fast (biological) carbon cycle.

Environmental factors, including experience, affect gene expression and thus cell differentiation.

The statement that environmental factors, including experience, affect gene expression and cell differentiation is true. Gene expression refers to the process by which information encoded in genes is used to produce functional products, such as proteins, in a cell. Environmental factors, such as external stimuli or experiences, can influence gene expression by activating or repressing specific genes.

In vertebrates, including humans, the environment plays a crucial role in shaping gene expression patterns. For example, exposure to certain stimuli or experiences can lead to changes in gene expression in neural cells, influencing their development and function. This phenomenon, known as environmental epigenetics, highlights the impact of the external environment on gene expression and subsequent cell differentiation.

Contrary to the other options, gene expression is not a predetermined result of mitotic lineages, nor is it independent of signals from the external environment. Additionally, cell differentiation typically occurs after gene expression, as the expression of specific genes guides the specialization of cells into different types during processes like neurogenesis.

Explanation:

Environmental factors caused many different traits in people, for instance the different skin pigments of people depend on where their ancestors came from. European descendents tend to absorb more sunlight and get sunburned easily, whereas African descendents have skin that is suitable for their environment. Other characteristics include immunity to malaria or the speed at which one's blood can carry oxygen. These traits came slowly through natural selection as people evolved to become suited for their environment.

Frogs have several adaptations that make them successful amphibians. Here are three key adaptations are mentioned below:

Moist Skin: Frogs have thin, moist skin that allows them to exchange gases, such as oxygen and carbon dioxide, through their skin. This adaptation is important because it enables them to breathe effectively in aquatic and terrestrial environments. The skin also helps them stay hydrated, as they can absorb water directly through their skin.

Webbed Feet: Most frogs have webbed feet, which are specialized for swimming and jumping. The webbing between their toes enables them to move efficiently through water, providing enhanced propulsion and maneuverability. On land, the webbing acts as a broad surface area for pushing against the ground, allowing frogs to make powerful leaps.

Tadpole Stage: The life cycle of frogs involves a unique larval stage known as the tadpole. Tadpoles are fully aquatic and have distinct adaptations for their aquatic lifestyle. They possess gills for breathing underwater, a tail for swimming, and a specialized mouth for filter-feeding on algae and other small organisms. As tadpoles undergo metamorphosis, they develop lungs for breathing air, lose their tails, and transition into their adult form.

These adaptations collectively enable frogs to thrive in diverse environments, making them well-suited for their amphibian lifestyle.

Explanation:

These periodic changes on Earth are a result of the five major ICE AGES that have occurred throughout Earth's history

The five major Ice Ages that throughout the Earth's history we're the following:

1. the Huronian: this occurred around 2.4 billion years ago

2. Cryogenian: this followed Huronian age, and it occurred around the period of 850 million years

3. Agondean-Saharan: this major ice age occur around 460 million years ago.

4. Karoo this is a period of about 360 million years

5. Quaternary is the present age, and it has been in existence since about 2.6 million years ago till the moment

Hence, in this case, the correct answer is Ice Ages

The changes taking place at Zappos illustrates numerous concepts related to organizational structure. The Holacracy system being adopted by the company removes the traditional line of command; instead tasks are delegated by employees to “circles” which are then serviced by members of those circles.

It focuses on efficiency of operations, as decisions are made in a decentralized fashion. Furthermore, the organization encourages employees to engage in learning and development to reach their potential, which is complemented by the company’s employee-first mentality.

It is difficult to ascertain whether these changes have been successful in so far as it is too early to ascertain the long-term effects. While the initial reports from the media focus on the positive aspects such as improved communication, job autonomy and growth, it remains to be seen if the company will continue to succeed or fall flat.
