Eukaryotic cells contain a nucleus and membrane-bound organelles.

Option B

<u>Explanation</u>:

Eukaryotic cells consists of membrane bound organelle, when we talk about organelle it is a structure within a living cell which is specialized. The organelles consist of nucleus, ''endoplasmic reticulum'', ''Golgi apparatus'', ''vacuoles'', ''lysosomes'', ''Mitochondria''. These organelles is surrounded by a phospholipid bilayer. With this foundation, the organelles have cell to control what enters and leaves it. These cells are controlled by selective permeability which has the enter and exit in control of any object.

This week, we'll be exploring the process of photosynthesis, including investigating some critical plant components that enable

Tpy6a [65]

1) Carbon dioxide

The carbon atoms present in CO2 are used by the plant in the formation of the organic molecular group (sugar).

2) Chlorophyll

Photosynthetic pigments present in chloroplasts, responsible for absorbing light from wavelengths between blue and yellow and reflecting different shades of green

3) Oxygen

Oxygen is the end product of photosynthesis, the result of the breakdown process of water molecules.

4) Stomata

Stomates have the function of performing gas exchange between the plant and the external environment. This structure is also responsible for the perspiration of the plant.

5) Sunlight

Energy source for the process of transforming light energy into chemical energy

6) Glucose

Final product of photosynthesis. Molecule that will be used by the plant to maintain its vital functions.

7) Water

Oxygen source that will be released as a gas at the end of the process.

Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetah.

Limiting factors are those factors in the ecosystem which can limit the growth of population of a species in an ecosystem. Predation and competition are two limiting factors in the ecosystem that can decrease or extinct the population of a species. Predation is a limiting factor in which predatory organisms are dependent upon a prey organisms. This is natures way of limiting the surplus growth of prey population and to maintain a balance in ecological community. Competition is a limiting factor in which one or more same or different type of organisms compete for the same resource in an ecosystem. The one which is more competitive will derive those resources other than the one which is less competitive.

According to the given data, it is evident that the population decline in predator cheetah and lion populations because of decline in zebra population but the decline in cheetah population is more than that of lion. It explains the fact that lion is more competitive than cheetah in deriving the food which is already limited. Therefore, lion outcompete cheetah.

in a phylogeny, information about relatedness is portrayed by the pattern of branching, not by the order of taxa at the tips of

MA_775_DIABLO [31]

On a phylogeny, the number of nodes separating two taxa indicates how closely related they are.

A given taxon typically includes several taxa of lower rank. Taxa are arranged in a hierarchy from kingdom to subspecies. Certain taxonomic categories, which are listed in descending order and include kingdom, phylum (in plants, division), class, order, family, genus, species, and subspecies or race, are universally accepted for the classification of protists, plants, and animals.

Kingdom, phylum, class, order, family, genus, and species are the orderly groups, going from largest to smallest. 2. Each level is referred to as a taxon (plural: taxa) or taxonomic category in taxonomic nomenclature.

A monohybrid cross is

Ne4ueva [31]

Answer:

A monohybrid cross is a cross between two organisms with different variations at one genetic chromosome of interest.[1][2] The character(s) being studied in a monohybrid cross are governed by two or multiple variations for a single locus. To carry out such a cross, each parent is chosen to be ratio.
