Answer:

As algas são organismos que anteriormente eram incluídos no Reino Plantae, porém atualmente pertencem ao Reino Protista, sendo a Ficologia (fico = algas; logia = estudo) o ramo da biologia que estuda esses seres: unicelular ou multicelular (filamentosas), eucariontes, fotossintetizantes e viventes em ambientes de água doce (rios, lagos ou superfícies úmidas) ou salgada (mares e oceanos).

Esses organismos autotróficos, dispostos na superfície oceânica (compondo o fitoplâncton), consomem o gás oxigênio dissolvido na água para a sua respiração e liberam através do processo fotossintético cerca de 70 a 90% do oxigênio contido na atmosfera. Recebendo, portanto, a denominação de pulmão do mundo, diferente do que muitos pensam que seja a Floresta Amazônica.

A reprodução assexuada pode ser tanto por divisão binária, isso nas unicelulares, onde a célula se divide ao meio; quanto por fragmentação, mecanismo de cisão de um segmento no talo nas algas multicelulares. Contudo, algumas espécies multicelulares reproduzem por zoosporia, utilizando-se de células flageladas que se desprendem do talo, locomovendo-se até um local favorável para o desenvolvimento.

ivanzaharov [21]

Answer:

Genetic engineering has multiple applications in different fields. Genetic engineering is the process by which alterations are made at the genetic level so that the final product is superior in quality and yield.

Explanation:

Following are few of it's applications:

<u>Medical field</u>- Genetic engineering is been used to produce insulin artificially, human growth hormones, anti hemophiliac factors, vaccines and other drugs.

<u>Agricultural industry</u>- It has been used to synthesize  improvised crops which give better yield and are pest resistant. E.g Flavr savr, a species of tomato which is more juicy and larger in size than regular tomatoes.

<u>Environment</u>- With the introduction of herbicide resistant corn, farmers reduced the use of tractors which in turn reduced the amount of greenhouse gases. Also, by imparting disease resistance to plants, a lot of plants are prevented from dying. In addition, the biodiversity of an area can be maintained.

An organism possesses one copy of each allele type for a given gene. It is said to be __________.
Sveta_85 [38]

Answer:

Heterozygous for the gene

Explanation:

Alleles are the possible alternative forms of a gene. An organism having two identical alleles of a gene is said to be homozygous for that gene. On the other hand, an organism having two dissimilar alleles for a gene is heterozygous for that gene.

For example, let's suppose that I^A and I^B are the two alleles for ABO blood type in humans. Here, an individual with one copy of I^A and one copy of I^B would be heterozygous for ABO blood type. On the other hand, genotypes I^AI^A and I^BI^B are homozygous for the ABO blood type gene.
