Answer:

scorpions are invertebrates but are insects

Answer:

A animal that is an vertebrate has a spine, and backbone. Some of these animals can be humans, dogs, cats, etc. But most 6 legged creatures, 8 legged creatures do not have a backbone.

To answer your question, no, scorpions are not vertebrates because they do not a spine and backbone.

Answer: B) because in higher plants, such as angiosperms and gymnosperms, the sporophyte is the dominant generation.

All of the following statements about ferns are correct except the gametophyte is a conspicuous generation. Therefore, the correct option is D.

In ferns the gametophyte is usually much smaller and less noticeable, whereas the sporophyte is the more noticeable generation. The sporophyte, the famous giant pearl fern plant, is a major stage in the fern life cycle. Gametes (eggs and sperm) are produced by the gametophyte, which is a small, autonomous stage responsible for sexual reproduction.

Therefore, the correct option is D.

Diabetes mellitus is a metabolic condition that occurs when the pancreas fails to produce enough insulin or when the body fails to use the insulin produced for glucose metabolism thereby leading to hyperglycaemia (increased blood glucose levels).

In pregnancy, diabetes is suspected in women who give this type of history:

Constant monitoring of Jacqueline is required to prevent complications during and after the pregnancy. This is done by performing series of tests and giving insulin injections when the need arises.

Answer:

b.

It depends upon the length of the fatty acids involved

Answer: B

Explanation: because it adapt to its environment to survive

The development of an organ system like a vascular system over a long period of time in plants is an example of evolution. Thus option A is correct.

Evolution is a series of events that have taken place in several years to make the species more advanced for the environment due to the introduction of multiple mutations in the genetic sequence.

During evolution, plants have gained the genetic mutation that codes for the vascular system which provide support and transports water in plants. So option A is correct.

The White House building is made of sandstone which is very porous as a result water is easily penetrated inside it which causes damage and make the walls of building weak.

The White House is made of gray-colored sandstone that is brought from quarry in Aquia, Virginia. The north and south porticos of white house building are constructed with red Seneca sandstone brought from Maryland. These sandstones are porous in which rainwater is easily penetrated in it that cause damage to the white house building so it is concluded that the building is made of porous sandstone.

Explanation:

La siguiente entrada tiene como objetivo realizar una breve explicación sobre las moléculas biológicas  lipídos y carbohidratos, las cuales son muy diversas ya que están formadas por carbono, lo cual hace que puedan formar muchos tipos de enlaces. Esta capacidad permite que las moléculas orgánicas  adopten muchas formas complejas, como son las cadenas, las ramificaciones y los anillos.

Las moléculas biológicas son grandes polímeros que sintetizas para poder enlazarse con otras subunidades mucho mas pequeñas conocidos como monómeros. Las cadenas de subunidades estan unidas por enlaces covalentes los cuales se forman por deshidratación, estas cadenas pueden romperse por hidrólisis. La moléculas biologicas más importantes son los carbohidratos, lípidos, proteínas y ácidos nucleicos.

Explanation:

Animals have special features that help them to live in a particular place. Therefore this features is called adaptation.

1] Aquatic plants have leaves that float on the surface of water.

2] Thier leaves are rarely have stomata.

3] Thier leaves can perform all the work without xylem.

4] They are usually lack cuticle layer in order to avoid excessive dryness.

Answer:

The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is frequently saturated with water.

Four characters of aquatic plants are as given below:

1) most aquatic plants donot need culticles or have thin culticles as cuticles prevent loss of water.

2) aquatic plants keep their stomata always open for they do not need to retain water.

3) on each side of their leaves are a number of stomata.

4) aquatic plants have less rigid structure since water pressure supports them.

Answer:

b. diffusion.

Explanation:

Diffusion can be defined as the movement of gas molecules from a region of high concentration to a region of lower concentration until an equilibrium is attained or reached. This mixing of gas molecules in the liquid or gaseous state is due to their kinetic energy of random motion i.e without requiring bulk motion.

This ultimately implies that, diffusion is a phenomenon through which gas molecules in either a gaseous or liquid state spread out in response to a concentration gradient, which is simply the difference in concentration of the gases across a space.

During diffusion, molecules move from areas of high concentration to areas of low concentration.

In this context, the process by which dissolved gases are exchanged between the blood and interstitial fluids is referred to as diffusion.

On a related note, this process is also referred to as internal respiration because it involves the exchange of oxygen gas and carbon (II) oxide gas between tissue cell and capillaries.

Answer:

Citral is a typical essential oil used in the food, cosmetic, and drug industries and has shown antimicrobial activity against microorganisms. Citral is unstable and hydrophobic under normal storage conditions, so it can easily lose its bactericide activity. Nanoemulsion technology is an excellent way to hydrophilize, microencapsulate, and protect this compound. In our studies, we used a mixed surfactant to form citral-in-water nanoemulsions, and attempted to optimize the formula for preparing nanoemulsions. Citral-in-water nanoemulsions formed at So 0.4 to 0.6 and ultrasonic power of 18 W for 120 seconds resulted in a droplet size of < 100 nm for nanoemulsions. The observed antimicrobial activities were significantly affected by the formulation of the nanoemulsions. The observed relationship between the formulation and activity can lead to the rational design of nanoemulsion-based delivery systems for essential oils, based on the desired function of antimicrobials in the food, cosmetics, and agrochemical industries.

Answer:

D. GGACCGTCGATCCTT

Explanation:

Mutation refers to any change in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. According to the question, an INVERSION mutation is a type of mutation in which a segment of a gene gets broken off and reattached in another way on the same DNA. Hence, the only change in inversion mutation is the arrangement of the nucleotide bases on the gene.

Considering the nucleotide sequence: GGACCGTCGATCTTC, the sequence that describes an occurrence of inversion mutation is: GGACCGTCGATCCTT because the segment TTC in the original sequence has been rearranged as CTT in the mutated sequence.

Answer:

Dark colour.

Explanation:

Dark fur color seems to have the greatest selective advantage because of their hard physical body which occurs due to extreme environmental conditions. The dark colour of mice occurs due to the high intensity of sunlight which increases melanin in their skin. These dark colour mice pass through a very hard and extreme environmental conditions so that's why Dark fur color seems to have the greatest selective advantage.
