Membrane molecules that use the energy of ATP to move ions against a concentration gradient are called PUMPS. This type of transport is called active transport.
Active transport is a type of transport that requires energy (e.g, ATP) to move molecules and/or ions against a concentration gradient.
In active transport, specific membrane transporter proteins referred to as pumps are used to move ions against an electrochemical gradient across biological membranes.
These protein pumps are fundamental for creating electrochemical gradients that are subsequently used by cells for diverse purposes (e.g., muscle contraction).

identify the explanations researchers suggested to explain differences in health and mortality by gender.
The differences in health and mortality by gender is a phenomenon for which researchers have many possible explanations.
There have been studies that have indicated that there is enough variation in the average health of males and females to conclude that there are factors at play that are affecting health.
Amongst the many possibilities, scientists have mentioned:
Gender-reliant genetic vulnerability Hormonal factorsDifferences in physiologyas the main possible reasons.
Hormones play a big part in the health of each individual and are vastly different between genders, along with the endless differences in physiology at a molecular level. These factors together may explain why some members of a gender are more vulnerable to genetic illness.

What is fertilizer?
Outside matter added to the ground to help plants grow
Oxygen and water added to the ground
Inorganic matter
Nitrogen-fixing bacteria in the ground
Answer: 3
Explanation:
Nitrogen, the most abundant element in our atmosphere, is crucial to life. Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow. But as with everything, balance is key: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants, and can also harm our environment. Plants that do not have enough nitrogen become yellowish and do not grow well and can have smaller flowers and fruits. Farmers can add nitrogen fertilizer to produce better crops, but too much can hurt plants and animals, and pollute our aquatic systems. Understanding the Nitrogen Cycle—how nitrogen moves from the atmosphere to earth, through soils and back to the atmosphere in an endless Cycle—can help us grow healthy crops and protect our environment.

where do photosynthetic organisms get the energy needed to make sugars during the light-independent/dark reactions?
Answer:
They use the glucose they have stored from previous photosynthesis reactions.
Explanation:
The dark reaction takes place external to the thylakoids. The energy from ATP and NADPH is used in this process to fix carbon dioxide (CO2).
What is light-independent/dark reactions?Carbon fixation, reduction, and regeneration are the three stages that make up the Calvin cycle, which is another term for the dark reactions that take place during photosynthesis.
The stroma of the chloroplast is the location where the light-independent process, also known as dark reactions or the Calvin-Benson cycle, is carried out. Carbon-based molecules are formed through a chain of chemical events that begin with carbon dioxide. The production of ATP and NADPH during the light-dependent process supplies these processes with the energy they need to proceed.

Organisms that obtain their energy from producers or other consumers are heterotrophs.
Kinetic energy is described as
Question 1 options:
Decreasing energy
Stored energy
Elastic
Movement
Answer:
elastic
Explanation:
The kinetic energy of a body can be decreased in two cases: When it is stored in the form of potential, for example: elastic or gravitational energy. Or when there are dissipative forces capable of transforming it into other forms of energy, as does the friction force. Which transforms kinetic energy into thermal energy.

An irrigation system is a structure made of tubes, hoses, and sprinkles; Its function is to water plants or crops with the correct amount of water and in an evenly way.
A simple irrigation system that will help grow plants at home is a plastic bottle with small holes connected to a hose with a tube that can lead the water from the hose to the bottle without losses. The bottle with its holes works as a sprinkler.
In conclusion, irrigation systems are in lawns, fields, or gardens, and they water the plants evenly so that they can grow. There are many types, but we can build a simple one with a bottle.

why is the digestive tract of the frog well vascularized
The digestive tract of the frog is well vascularized because it aids in the absorption of nutrients.
The digestive tract of a frog is a hollow long tube that extends from the mouth to the anus which helps in the ingestion and digestion of food.
The digestive tract of frog has the following characteristics:
alimentary canal of the frog is not long, that is, it is short. It has accessory organs of digestion such as liver, gall bladder and pancreas.All the digested food substances are absorbed at the small intestine due to the presence of microvilli.
This microvilli is made up of a central core that is vascularized, that is, it contains artery, vein and lymphatic capillary.
Therefore, the vascularized microvilli of the small intestine of frog help in the absorption of nutrients.
