Answer:

O Take in slightly less calories than you use daily

Explanation:

It has been shown that the healthiest diets to lose weight are those where individuals consume fewer calories than normal and simultaneously by taking care of consuming all essential nutrients in adequate quantities.  

The essential nutrients to be consumed in a healthy diet include:

1- macronutrients, especially proteins (amino acids) to avoid muscle loss as well as normal metabolic functions, and fats, which are required to absorb some micronutrients (i.e., liposoluble vitamins)

2- micronutrients, which include vitamins (e.g., vitamin D, vitamin C, etc) and minerals (e.g., iron, calcium, etc).

Answer: A

Explanation: Hull Fouling

The introduction of Caulerpa, also known as killer algae, into California was ultimately the result of the aquarium trade in exotic, nonnative aquatic species. The correct option is b.

Exotic species are those that have been introduced, either intentionally or unintentionally, by humans into an ecosystem where they did not evolve. Such introductions are most likely a natural occurrence.

Endemic species are those that are found only in one region and nowhere else on the planet.

Invasive species have the potential to extirpate native plants and animals, reduce biodiversity, compete with native organisms for limited resources, and alter habitats.

This has the potential to have significant economic consequences as well as fundamental disruptions to the coastal and Great Lakes ecosystems.

Caulerpa, also known as killer algae, was introduced into California as a result of the aquarium trade in exotic, nonnative aquatic species.

Thus, the correct option is b.

Answer:

because it holds the information needed to conduct most of the cell's functions.

Cell membrane controls the transport of molecules across the cell and its external environment, Thus, it is called as the brain of the cell.

Cell membrane regulates most of the cellular activities through the property of selective permeability.

It is responsible for maintaining the cellular equilibrium through influx and efflux of ions and molecules.

There are various receptors present on the cell membrane which regulates the vital biochemical processes taking place in the body.

Cell membrane functions in the cell-cell recognition and cell signalling through various receptors.

Cell membrane is important in regulating body homeostasis. It offers the protective environment to the cell.

Control and regulation of activities is processed through brain.

Therefore, cell membrane is considered as the brain of the cell.

Answer:

Triploid

Explanation:

The process whereby gametes produced by different sexes of the same species of organism come together is called FERTILIZATION. A gamete is said to be HAPLOID (n) if it contains one set of chromosomes while it is DIPLOID (2n) if it contains two sets of chromosomes.

Hence, if an haploid (n) and diploid (2n) gamete unites, a zygote that is TRIPLOID (3n) emerges or forms. A triploid zygote will have three sets of chromosomes i.e. n + 2n = 3n.

Answer:

C : Proteins

Explanation:

(Can I get brainlest?)

Proteins are the molecules that provide building blocks for tissues, transports other molecules, and helps regulate certain reactions in the human body. The correct option is C.

A protein is a found naturally, extremely complex substance composed of amino acid residues linked together by peptide bonds.

Proteins are found in all living life forms and contain a variety of important biological compounds such as enzymes, hormones, and antibodies.

Proteins are massive complex molecules that perform numerous important functions in the body.

They are essential for the structure, function, and regulation of the body's tissues and organs and do the majority of the work in cells.

Proteins are molecules that serve as foundation for tissues, transport other molecules, and aid in the regulation of certain bodily reactions.

light intensity does not affect the rate of photosynthesis .

The process in which plants, algae and certain bacteria use light energy of sunlight, water, carbon dioxide and convert light them into chemical energy and starch. called as photosynthesis.

Photosynthesis occur in special organelles named chloroplast which has its own DNA, genes and hence can synthesize their own proteins.

Chloroplasts have stroma, fluid, and stack of thylakoids known as grana, three types of chlorophyll such as chlorophyll a, chlorophyll b, and carotenoids.

Oxygenic photosynthesis is  commonly observed in plants, algae and cyanobacteria where electrons are transferred from water to carbon dioxide by using light energy, to produce energy,  oxygen is produced along with carbohydrates.

Answer:

One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.

Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.

Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics.

Explanation:

One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.

The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.

Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents. Currents are movements of ocean water in a continuous flow, created largely by surface winds but also partly by temperature and salinity gradients, Earth’s rotation, and tides. Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.

Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.
