Ans.

Land plants were evolved on the Earth around 850 million years ago. The ancestors of plants are considered as plant-like single cell organisms. These organisms include tiny protists, that were capable of performing photosynthesis as nearly all land plants perform photosynthesis. An example of photosynthetic protist is green alga.

Thus, 'the ancestors of land plants likely evolved from single-cell, photosynthetic protists, such as green algae.'

The ancestors of land plants likely evolved from green algae.

Further Explanation:

Plant grows in a particular region and mainly makes own food. Plants consists pigments that help in synthesis of food. Some plants are seedless and some plants make seed. Seedless plant does not make seeds; they make spores for example ferns, liverworts, horsetails and mosses. Seed plant makes seed and reproduces like flower plant.

Land plants manly evolved on the Earth approximately eight hundred fifty million years ago. Plant-like single cell organisms are referred as main ancestors of plants. These organisms mainly consists tiny protists that are capable of performing photosynthesis as nearly all land plants perform photosynthesis. An example of photosynthetic protista is green algae.

Algae, phytoplankton, bacteria and plants, are photosynthetic in nature. They use sunlight to make sugar, which then converts into energy. They make their food by photosynthesis. Photosynthetic organisms are mainly green because they contain a chlorophyll pigment which helps in absorbing light.

The theory of endosymbiosis is based on Multiple Choice similarities between chloroplasts and other organelles in animals. evide

Arisa [49]

Answer:

the observations that chloroplasts and mitochondria resemble bacteria

Explanation:

The Endosymbiotic Theory is a theory that enables us to understand the origin of eukaryotic cells. The Endosymbiotic Theory posits that the mitochondria and chloroplast, which are organelles found in the eukaryotic cells, were once prokaryotic microbes that were first ingested by amoeba-like organisms and subsequently evolved by developing a symbiotic relationship with them. Some of the most important lines of evidence that supports this theory are: 1-chloroplasts and mitochondria resemble prokaryotic cells, i.e., they have a similar size, replicate by binary fission and there are unicellular eukaryotic protists that have filamentous temperature-sensitive proteins at their division plane (similarly to bacteria), and 2- chloroplasts and mitochondria are organelles with their own DNA and their own ribosomes (which are similar to those of bacteria).

Which type of mutation affects the largest number of genes

SashulF [63]

Answer:

Chromosomal Mutation

Explanation:

The development and function of an organism is in large part controlled by genes. Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression. Because a change in the DNA sequence affects all copies of the encoded protein, mutations can be particularly damaging to a cell or organism. In contrast, any alterations in the sequences of RNA or protein molecules that occur during their synthesis are less serious because many copies of each RNA and protein are synthesized.

Geneticists often distinguish between the genotype and phenotype of an organism. Strictly speaking, the entire set of genes carried by an individual is its genotype, whereas the function and physical appearance of an individual is referred to as its phenotype. However, the two terms commonly are used in a more restricted sense: genotype usually denotes whether an individual carries mutations in a single gene (or a small number of genes), and phenotype denotes the physical and functional consequences of that genotype.

HIV can remain latent for several years and not cause any symptoms in its host. What viral reproduction cycle is occurring durin

lakkis [162]

Answer:

The lytic cycle.

Explanation:

HIV is a retrovirus that has a special enzyme called transcriptase reverse, which can synthesize DNA using RNA as a template. This replication system is particularly useful for the virus because the DNA synthesized from the RNA viral genome can be then integrated into the human chromosomes and stay inactive for years. This is called a lysogenic cycle and is characterized by a latency of the virus and an integration to the host DNA.

When there is a triggering event, this latent virus can be excised from the human chromosome and start producing copies of itself using the host machinery. Then the virions are assembled and after that they lyse the host cell and release new infective units that can then infect neighboring cells. This is called the lytic cycle of the virus and is the reproduction cycle that occurs when a person moves into the acquired immunodeficiency syndrome (AIDS) stage of HIV infection.
