Answer:

a way to inform conservation efforts based on genetic information from species

Explanation:

Genetic studies in wildlife and captivity species provide significant information to understand aspects regarding the biology and ecology of species, especially endangered species. Many discoveries have been useful to solve several taxonomic issues, determine the risk of diseases, and explain reproductive problems, among other problems. What is even more important is that genetic knowledge helps to plan management programs and conservation. Together with other areas related to behavior and conservation, genetic knowledge provides the basis to carry out successful conservation strategies.  

Answer:

Because it controls all the activities in the cell

The nucleus is considered to be one of the most important structures of eukaryotic cells as it serves the function of information storage, retrieval and duplication of genetic information. It is a double membrane-bound organelle that harbours the genetic material in the form of chromatin.

A sustainable system refers to producing less or probably non-existent debris that are caused by the production of a particular material (i.e. produce, energy). This is a sustainable form of production of coupling algae growth and fish farming because you no longer need the supply of fish feed from other sources that are made artificially but rather, you are using the available algae growth that you are culturing. Farm fishing alone is non-renewable because this produces much waste that can directly harm the environment.

An integrated aquaculture system of fish farming with kelp farming is a sustainable system as both system exchange resources and thus reduce wastage of resources.

An integrated aquaculture system is an aquaculture system which combines several forms of aquaculture together.

For example, kelp farming is a form of aquaculture which can be integrated with another form of aquaculture such as fish farming.

Integrating fish farming with kelp farming is a sustainable system as both system provides what the other needs.

The kelps serve as food to fish while fish waste serve as manure for kelps.

Therefore, integrating fish farming and kelp farming is a form of a sustainable system.

Answer:

This question is incomplete, it is asking to fill in the missing gaps as follows:

The principle of dominance is a ______ inheritance pattern.

It’s states traits that are ______ mask the traits that are______

The answers to the missing gaps are: MENDELIAN, DOMINANT, RECESSIVE

Explanation:

Gregor Mendel proposed the principles that govern inheritance. These principles are called MENDELIAN inheritance pattern because they align with or follow the principles of Mendel. One of these principles by Mendel is the LAW OF DOMINANCE.

Mendel has previously stated that there are two alleles for each gene. Each contrasting allele encodes a different phenotype. However, the law of dominance states that one of these two alleles called DOMINANT allele has the ability to mask the phenotypic expression of the other allele called RECESSIVE allele. In other words, a dominant trait will mask the recessive trait.

For example, in a gene Tt, allele 'T' for tallness is dominant and hence, will mask the phenotypic expression of allele 't' for shortness. This means that the tall trait (dominant) will mask the short trait (recessive) as explained by Mendel's law of dominance.

Forms of tropism include phototropism (response to light), geotropism (response to gravity), chemotropism (response to particular substances), hydrotropism (response to water), thigmotropism (response to mechanical stimulation), traumatotropism (response to wound lesion), and galvanotropism, or electrotropism (response to electric current). 

Tropism is a response to certain stimuli. A positive tropism is moving towards the stimuli, while a negative tropism is moving away from a stimuli.

Positive Phototropism - Growing towards light

Negative Phototropism - Growing away from light

Positive Thigmotropism- Moving towards touch

Negative Thigmotropism- Moving away from touch

Positive Hydrotropism - Growing towards water

Negative Hydrotropism - Growing away from water

Positive Gravitropism - Growing towards ground

Answer:

The antibody has a molecular weight of 150 kD and consists of four subunits: two subunits of 50 kD and two subunits of 25 kD, which are bonded by covalent bonds.

Explanation:

Sodium dodecyl sulfate (SDS) is a detergent used to alter and denature proteins before gel electrophoresis. SDS can break hydrophobic interactions and hydrogen (H) bonds, but this detergent does not break down disulfide bonds, which is a type of covalent bond between two sulfur atoms. Moreover, mercaptoethanol is a reducing agent used to break disulfide bonds. In this case, it is expected that mercaptoethanol can break disulfide bonds between the four subunits of the mature antibody, thereby yielding two bands corresponding to the 50 kD and 25 kD bands (two subunits of 50 kD + two subunits of 25 kD = 150 kD).

Answer:

cuticle

In some higher plants, the cuticle is a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss. It consists of cutin, a waxy, water-repellent substance allied to suberin, which is found in the cell walls of corky tissue.

adapted( function)

The cuticle reduces the rate of water loss from the leaf surface. Other leaves may have small hairs (trichomes) on the leaf surface. ... They can also reduce the rate of transpiration by blocking air flow across the leaf surface.

palisade mesophyll

Light absorption happens in the palisade mesophyll tissue of the leaf. Palisade cells are column shaped and packed with many chloroplasts . They are arranged closely together so that a lot of light energy can be absorbed.

adapted ( function)

The palisade mesophyll layer of the leaf is adapted to absorb light efficiently. The cells: are packed with many chloroplasts. are column-shaped and arranged closely together

spongy mesophyll

Spongy mesophyll tissue is packed loosely for efficient gas exchange. The spongy mesophyll cells are covered by a thin layer of water. Gases dissolve in this water as they move into and out of the cells. ... To enter the leaf, gases diffuse through small pores called stomata.

adapted (function)

Spongy mesophyll tissue is packed loosely for efficient gas exchange. The spongy mesophyll cells are covered by a thin layer of water.When the plant is photosynthesising during the day, these features allow carbon dioxide to diffuse into the spongy mesophyll cells, and oxygen to diffuse out of them

Guard cell

Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. Light is the main trigger for the opening or closing. Each guard cell has a relatively thick cuticle on the pore-side and a thin one opposite it.

Adapted (function)

Guard cells are adapted to their function by allowing gas exchange and controlling water loss within the leaf. The size of the stomatal opening is used by the plant to control the rate of transpiration and therefore limit the levels of water loss from the leaf. This helps to stop the plant from wilting

Haploid+ Haploid = Diploid represents fertilization. So, the correct option is (C).

Fertilization is defined as the process in which two gametes where one male and one female first form a zygote and then lead to the development of an embryo.

These germ cells are cells that give rise to gametes – either egg cells that are female gametes or sperm cells that are male gametes.

These germ cells are the only cells that can undergo both mitosis and meiosis. These are the diploid cells present in the gonads. After meiosis, haploid gametes are produced. In fertilization two haploid gametes fuse (n+n) and form a diploid zygote (2n)

Explanation:

An inversion is a genetic phenomenon that occurs when a chromosome breaks into two genomic sites, thereby the resulting DNA fragment is reversed and subsequently inserted into the same chromosome location. A pericentric inversion occurs when the chromosome breaks are located on opposite arms or sides of the chromosomal centromere. Moreover, crossing over (or recombination) is the exchange of genetic material between non-sister chromatids during gamete production. An inversion carrier, as in this case the woman who is heterozygous for a pericentric inversion, can produce four types of gametes. If there is no crossing over, half the chromatids will produce normal gametes (without the recombination event) and half the chromatids will produce balanced gametes that will transmit the pericentric inverted chromosome. On the other hand, if there is crossing over, half the chromatids will have one duplication on the first chromosome arm together with a deletion on the second chromosome arm, and the remaining half of the chromatids will have an inverse arrangement.

Living system can be defined as the internal systems of organisms and how materials circulate within organisms.

Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.

Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.

Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc., which are typically used for carrying out various bodily functions such as respiration, metabolism, digestion, etc.

A sensory system can be defined as components of the central nervous system (CNS) which comprises of the brain, neural tissues or pathways and sensory neurons responsible for sensory functions, perception and processing sensory informations such as sound, light, heat, etc.

Basically, the central nervous system (CNS) interprete the neural signals that are generated from stimuli that are detected by the sensory system. The five (5) main sense organs in the sensory system are: skin, tongue, ears, nose and the eyes.

Generally, the nervous system found in living organisms such as humans, comprises of two (2) major components or systems; a central nervous system (CNS) and a peripheral nervous system (PNS).

The correct sequential order for the transmission of a signal through the nervous system;

1. Nerve impulse is triggered.

2. Synaptic vesicles release neurotransmitters.
