Answer:

They produce oxygen and act as primary producer

Explanation:

Marine algae are important to marine and terrestrial population because they are responsible for fixing carbon dioxide to produce oxygen as well as act as the primary producer in the marine ecosystem.

A large percentage of the oxygen available for aerobic respiration in several terrestrial organisms are produced by marine algae through the process of photosynthesis.

Also, marine algae act as the primary producer in the food chain and food web of the marine ecosystem. Without them, the food chain would be broken and biological activities would be disrupted in the marine ecosystem.

If a bullet were to penetrate a lung, which three anterior thoracic body cavities would it enter, and which layer of the serous

Stella [2.4K]

Answer:

First of all is ventral: cavity that makes up the thoracic and abdominopelvic cavity ventral: cavity that makes up the thoracic and abdominopelvic cavity

Secondly it is thoracic: chest cavity

And thirdly it is pleural cavities: which consist of ths lung cavity

That is it will encounter tbe parietal layer of the serous membrane first :lines cavity

Explanation:

The organs in the body are safely guarded by the membrane, cavities and sheaths(which has different compartment). They act to protect the organs in the body like lungs.

A person who was shot with a gun, the bullet must pass the body cavities when moving to the lungs. It must first pass through the 3 cavities before it arrives at the lungs that is the ventral cavity, thoracic cavity and the pleural cavity. The serous membrane is usually found within the walls of the thoracic cavity.

Answer:

First, you need to retrieve the FASTA sequences of the already sequenced genes. After that, you should make a sequence alignment on a software like CLUSTALW (https://www.ebi.ac.uk/Tools/msa/clustalw2/) to seek for the conserved regions of the gene. Based on this regions, you will design your FISH probe, which for bacteria can start in 33 bp (Ming Tan et al., 2019), but a 200 bp probe is a very suitable size. There are several companies that fabricates this custom probes, and sell all the reagents to perform the experiments. Having this, you will perform your FISH experiment to see which cells are actively degrading Toluene.

What is the biological significance of genetic diversity between populations? What is the biological significance of genetic div

mrs_skeptik [129]

Explanation:

A) Genes for traits conferring an advantage to local conditions make microevolution possible.

For example, Galapagos finches show variation in beak sizes and shapes related to their niches and available food source; the finches developed adaptations to their environment. Their specialized beaks allow them to adequately exploit the available resources, by utilizing the more abundant food source.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell. Crossing over, independent assortment, and random fertilization ensure genetic variation.

This variation refers to the genetic characteristics present within a species; they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring an advantage.

Additionally, natural selection, mutation, genetic drift and gene flow lead to microevolution; over time, this is seen as changes to allelic frequencies within a population
