I think this is partly true and partly false. It is partly true because plants undergo in a process called photosynthesis and it is sunlight that makes them do this. It is partly not true because literally the sunlight can't be considered a food source because it actually don't give you food.

This is incorrect. Sunlight is a form of energy that can be utilised, for example by plants, to produce a food source during the process of photosynthesis. In this example, photosynthesis uses sunlight, carbon dioxide and water to produce glucose (food).

____ happens when a lineage splits into two or more lines of descent.

Evgesh-ka [11]

When a lineage splits into multiple line of descents, then, it leads to speciation. It is a process by which a single population evolves into different species. The process of speciation leads to the development of two or more species as the lineages are splitted. These two evolved species are genetically independent.

Hence, the blank can be filled with 'speciation'.

Opsonization.

Explanation:

Complement proteins and antibodies coat a microorganism and provide binding sites, enabling macrophages and neutrophils to phagocytize the organism. This phenomenon is termed opsonization.

Opsonization occurs as a result of binding of a molecule called opsonin to the epitope of a pathogen.

Opsonization helps the immune system to select and kill the infected cells instead of targeting all the cells in general.

CAN SOMEONE PLEASEEEE HELP ME WITH THIS SCIENCE QUESTION I WILL MARK YOU BRAINLIEST !!!

Answer:

When the rule of 70 applies to population, dividing 70 by the percentage of population growth should equal the time (in years) that the population needs to be double (option A)

Explanation:

The rule of 70 is useful to calculate the time in which a variable of any type can be duplicated. The calculation is done by dividing the number 70 by the percentage of growth of the variable.

If the rule of 70 is applied to the population, it is possible to calculate, based on its growth rate, the time that population would need to double.

If, for example, the growth rate of a population is 3 percent:

70 / 3 = 23,33

This indicates that a population, with a growth rate of 3% would need about 23,33 years to double.

Answer:

This is a Desert Biome.

Explanation:

There are hot deserts and cold desert.
Here the question is stating about the hot deserts.

Hot deserts are characterized by extremely hot and arid climate.
Average annual range of rainfall is as low as 25 cm.
Deserts lack vegetation except at some patches.
Plants that survive in hot deserts have several adaptation to check the loss of water through transpiration.
These adaptation include, succulent stems, cuticularized epidermis, Reduction of leaves into spines or thorns, stems modified into phylloclades and deep roots to absorb water.

Biologists use ball-and-stick models to study complex molecules by representing atoms with balls and bonds with sticks. DNA is a

Vitek1552 [10]

Most models can't incorporate all the details of complex natural phenomena. For example, when measuring distances around the Earth it's convenient to model the Earth as a sphere, but this doesn't incorporate variations in distance because of mountain ranges, valleys and other topological features the traveler must traverse. Incorporating these additional details would make the model too complex for easy use. Since models must be simple enough that you can use them to make predictions, they often leave out some of the details.

ALSO.

The conformation of molecules are based on probability. It fails to take into account the electronegativity of individual atoms. And it is ineffective in showing inorganic interactions with metals and such.
