Answer:

Plums have high concentrations of anthocyanin, which absorbs light between 500 nm and 600 nm but reflects blue-purple wavelengths.

Spinach leaves have a high concentration of chlorophylls, which absorb light of lower wavelengths but reflect green ones.

Explanation:

White light is a mixture of the visible spectrum of light. Whenever white light meets a pigment, some wavelengths are absorbed by the pigments while others are reflected. The reflected spectrum is perceived as color and determined to be the pigment color or the color of an object or organism.

The color that tissue or vegetal organ express will depend on the pigment concentration or the combination of many of them.

The green color is normal in most vegetable species. Chlorophyll is responsible for this coloration, present in almost every vegetable species. This pigment absorbs blue and red wavelengths. Blue wavelengths a between 420-470 nm. But they reflect spectrums of green wavelengths, meaning that the expressed color is green in different tones.

On the other hand, many fruits -blueberries, cherries, plums, or grapes- and flowers express a high concentration of anthocyanin, a pigment that reflects spectrums of red, blue, and purple wavelengths. This pigment absorbs light of 250, 370, and 500-600 nm. Yellow and orange wavelengths correspond to 500-600 nm.

Plums:

Spinach leaves:

(a) Plums have high engagements of anthocyanin, which absorbs light between 500 nm and 600 nm but reflects blue-purple wavelengths.

(b) Spinach leaves have a high engagement of chlorophylls, which absorb light of lower wavelengths but reflect green ones.

Answer:

The nuclear division that forms haploid cells, which is called meiosis, is related to mitosis. As you have learned, mitosis is the part of a cell reproduction cycle that results in identical daughter nuclei that are also genetically identical to the original parent nucleus.

Explanation:

The nuclear division that forms haploid cells, which is called meiosis, is related to mitosis. As you have learned, mitosis is the part of a cell reproduction cycle that results in identical daughter nuclei that are also genetically identical to the original parent nucleus.

Answer:

In general, mitosis (division of the nucleus) is preceded by the S stage of interphase (during which the DNA is replicated) and is often followed by telophase and cytokinesis; which divides the cytoplasm, organelles and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components.

Explanation:

The different stages of Mitosis all together define the mitotic (M) phase of an animal cell cycle—the division of the mother cell into two genetically identical daughter cells.Meiosis results in four haploid daughter cells by undergoing one round of DNA replication followed by two divisions. Homologous chromosomes are separated in the first division.

Answer: The steps in reproduction of angiosperms that animals assist with is

a.) Pollination

Explanation:

ANGIOSPERMS are flowering plants that forms the largest group in the plant kingdom. The angiosperms are more highly evolved than other plants because they have an abundance of water- conducting vessels and bear seeds which are protected within fruits. Fruits develop from the ovaries of flowers, the female reproductive organ of the angiosperms.

Pollination is only the first step in the process of sexual reproduction in flowering plants. It is followed by fertilization and development of the zygote. These steps change the flower into a fruit enclosing seeds. Pollination in flowering plants involves the transfer of pollen grains from an anther to a receptive stigma.

Pollination depends on external pollinating agents known as pollinators. These include

--> insects and

--> animals such as birds, squirrel,bats and snails.

Animals such as birds perceive red colour more clearly than insects. They are also larger than insects and unlike insects have a poor sense of smell. As a result, flowers of plants that are pollinated by birds are usually Res with no scent. While flowers pollinated by insects are scented and produce nectar. As they visit the flower, they become covered with the pollen from the mature anthers of the flower. These pollen grains are eventually transferred to the stigma of another flower of the same species leading to fertilization which is a step in plant reproduction. Therefore, pollination is a step in reproduction of angiosperms that animals assist.

Answer:

B. Seed dispersal

Explanation:

Seed dispersion is an ecological process very important in keeping ecosystemic biodiversity and in vegetal communities regeneration. There are many types of dispersion. But probably, zoocory is one of the most significant types of seed dispersion.

There are two types of zoocory:

By endozoocory, herbivores are significant not only for dispersing the seeds but also for scarifying them. When seeds pass along the digestive system of the animals, the whole digestive process eliminates or debilitates the cuticle and other external structures, increasing the proportion and speed of germination.

Many vertebrates are involved in seed dispersion, but birds and frugivorous bats play an important role in dispersing seeds far away from the parental plant, playing an important role in the natural ecosystem regeneration processes.

Answer:

Chlorophyll B

Answer:

The correct answer is - B. breaking the bond between the 2nd and 3rd.

Explanation:

ATP molecule is known as cellular currency as it provides energy for cellular functions. ATP released energy when one phosphate group is removed or eliminated by breaking a phosphoanhydride bond. The rebreaking of this bond and removal is known as hydrolysis, and ATP is converted to adenosine diphosphate (ADP).

Breaking the bond between the 2nd and 3rd phosphate groups provides a very high amount of energy. There is also additional energy released when phosphate is removed from ADP to form adenosine monophosphate (AMP).

b) x: fin

   y: lateral line

   z: swim bladder  

Explanation:

The dorsal fin is found in the dorsal region of the fish body. Depending on the species, there can be one or two dorsal fins. Membranous structures and bony or cartilaginous ratios compose the fins. One of the main functions is to stabilize the body in water, providing equilibrium. When the dorsal fin is erect, it acts as a keel, helping the fish not to turn aside. Fishes also use these fins as protection because the cartilaginous or bony ratios act as spines. The animal uses these spines to defend itself from predators. The morphological variety of dorsal fins in the different species is used in taxonomy.

The Lateral Line is a system or sensory organ composed of special receptors called neuromasts, which can be found all along the lateral region of the animal. The lateral line perceives information from the environment, such as light, sound, or water movement, among others. These signs are translated into nervous messages. The lateral line is useful to detect prey, predators, other animals moving, objects, etcetera. It is significant for intraspecific interaction, especially during swimming motions in schools. The lateral line receives perturbations of short distance, generated by other living beings or by objects. Some studies confirm that the lateral line is also sensitive to chemical stimuli.

The swim bladder is a neumatic sac-like structure filled with gases coming from the blood. Its main function is to allow neutral floating and let the animal in suspension at any depth, with no need for muscular effort. The animal can regulate the size of the bladder. This organ can be found in most pelagic fishes, while the benthonic ones or the ones that actively swim lack it.

Answer:

1 deltoid: striated

2 triceps: striated

3 heart: cardiac

4 sartorius: striated

5 intestine: smooth

6 veins: smooth

7 biceps: striated

8 trapezius: striated

9 stomach: smooth

10 gastrocnemius: striated

Explanation:

Striated muscle is a type of tissue composed of repeated functional units called sarcomeres, which are the basic contractile unit of the muscle fiber. The striated appearance is caused by repeating bands of actin and myosin proteins. Striated muscle tissue is subdivided into two major parts: 1-cardiac muscle and 2-skeletal muscle. Skeletal muscle is a highly dynamic tissue that is mostly attached by tendons to the bones in the skeleton. This voluntary tissue (skeletal muscle tissue) is composed of multiple fascicles or bundles of muscle fibers. Moreover, cardiac muscle tissue, also known as myocardium, is a type of striated muscle that contracts and releases involuntarily, composed of cells called myocytes present in the heart. Finally, smooth muscle is a type of involuntary and non-striated muscle tissue localized within the walls of organs/structures (i.e., intestine, esophagus, stomach, uterus, urethra, bladder, blood vessels, etc.).

Answer:

It is believed that insects are so successful because they have a protective shell or exoskeleton, they are small, and they can fly. Their small size and ability to fly permits escape from enemies and dispersal to new environments. ... In addition, insects can produce large numbers of offspring relatively quickly.

There are a number of important aspects that contribute to the success of the Class Insecta, which includes insects. The factors are their size, thin exoskeleton, reproduction, etc.

First off, because of their modest size and effective body composition, they may occupy a variety of environments and fill a variety of biological niches.

Insects have a thin exoskeleton that allows for flexibility and motion as well as protection and support.

Because of their diminutive size, they can access a variety of microhabitats, cracks, and supplies that larger species cannot.

In addition, insects have remarkable methods and capacities for reproduction. The majority of insects reproduce quickly and give birth to numerous young.

They use a variety of reproductive techniques, such as internal fertilisation and complex courtship rituals.

Thus, the small size, effective body structure, variety of reproductive techniques, flexibility, and resilience of Class Insecta are factors in their success.

Thus, these elements have made it possible for insects to survive in a variety of habitats, use a range of resources, and play essential roles in ecosystems as pollinators, decomposers, predators, and prey.
