Leaf vein patterns in monocot flowering plants are parallel.
TRUE
or
FALSE
Answer:
The given statement is true.
Explanation:
Monocot plants leaves have different kind of venation to dicot plants. All plant Leaf veins are arranged in a reticulate arrangement or in a parallel through the length of the leaf throughout the leaf.
In most of the monocot flowering species, monocot leaves have parallel venation arrangement while dicots have reticulate venation.
Parallel venation is an evolved adaptive feature of monocots over dicots as it provides the benefit of transportation to the end of the leaves.
Thus, the statement is true.

C. The chromosomes coil up and condense. D. The cell is developing and going about its daily activities.
Answer:
The correct answer is option b. the chromosomes line up.
Explanation:
Metaphase is the phase which takes place between prophase and anaphase. It is mitotic phase in which microtubules attached. The chromosomes line up during this phase.
Metaphase is characterized by the attachment of spindle to the chromosomes. Attachment is complete by the microtubules of spindle.
Thus, the correct answer is option b.the chromosome line up.

All of the following wavelengths can be seen by the human eye EXCEPT red light waves infrared waves blue light waves violet light waves
The human eye can see visible light in the range of 380 nm to 740 nm, which includes colors red through violet. The wavelengths outside this range, such as infrared waves, cannot be seen.
The human eye can see light with wavelengths that range from about 380 nm to 740 nm. This range includes the colors of the rainbow, which can be remembered by the mnemonic ROY G BIV - for Red, Orange, Yellow, Green, Blue, Indigo, and Violet. However, the wavelengths that fall outside of this visible spectrum, such as infrared waves, cannot be seen by the human eye. Infrared light has longer wavelengths than the visible red light, and humans perceive this as heat rather than light.
Visible light is composed of a spectrum of colors that include red light waves, blue light waves, and violet light waves. However, all wavelengths can't be seen by the human eye; specifically, infrared waves are outside the visible range. Thus, all of the listed wavelengths can be seen by the human eye except infrared waves.

What happens to macromolecules from food during digestion?
which carbohydrate are used as structural support instead of energy storage
Carbohydrates are used as fuels and building material, organic molecules made of sugars and their polymers that is large molecules consisting of many identical or similar subunits connected together through polymerization. Carbohydrates has three categories that is according to the number of simple sugars: (1) Mono saccharides (2) Oligo saccharides and (3) Polysaccharides. Polysaccharides is formed by enzyme-meditated condensation reactions and is stored in the muscle and liver of vertebrates. These are macromolecules that are polymers of a few hundred or thousand monosaccharides. Starch and glycogen are examples of polysaccharide that is use as energy storage while cellulose and chitin are polysaccharides that is use as structural support. Cellulose is a liner unbranched polymer of glucose most abundant organic molecule on the planet, reinforces plant cell walls and cannot be digested by most animals because they lack the enzyme that can hydrolyze the linkage in BLANK. While Chitin is a structural polysaccharide that is a polymer of an amino sugar, forms the exoskeleton of arthropods (insects, crawfish) and found in the cell walls of some fungi.

Which of the following cavities would a surgeon performing an operation on the intestines have to open?
A) Abdominopelvic and abdominal
B) Thoracic and abdominal
C) Abdominopelvic and thoracic
D) Thoracic and pericardial
Final answer:
A surgeon operating on the intestines would have to open the A) Abdominopelvic and abdominal cavities. The pleural cavity, which is associated with the lungs, is part of the thoracic cavity.
Explanation:
The question asks about the body cavity a surgeon would open to operate on the intestines. The correct answer is A) Abdominopelvic and abdominal. The abdominopelvic cavity is the largest in the body and includes both the abdominal cavity (housing the digestive organs, such as the intestines) and the pelvic cavity (housing the reproductive organs).
As for the pleural cavity, it is part of the thoracic cavity which also contains the pericardial cavity surrounding the heart. These cavities are all located within the larger anterior (ventral) cavity. Thus, a surgeon must open the abdominopelvic cavity to perform operations on the intestines.

which of the following are attributed to linnaeus?
Carl Linnaeus is celebrated for three main contributions: developing the taxonomic system for classifying organisms into related groups, establishing the binomial nomenclature for naming organisms, and systematically grouping together organisms sharing common traits.
Explanation:Carl Linnaeus, a Swedish botanist, zoologist, and physician, is significantly credited with several achievements in biology. Among his works, three attributes stand out:
He developed a taxonomic system for categorizing organisms into related groups. This hierarchical model featured classifications such as kingdom, class, order, family, genus, and species, and has since been expanded to include additional levels like domain, phylum, subclass, superorder, tribe etc.Linnaeus introduced the binomial nomenclature, a system of naming organisms using two unique Latin names – the genus name and the species name. This vastly reduced confusion caused by regional differences in common names of organisms.He grouped organisms that shared common traits creating categories like 'mammals' for animals with mammary glands, demonstrating his systematic approach to classification.These contributions of Linnaeus have laid the groundwork for modern taxonomy and biological nomenclature.

All of the following are nonspecific defense responses made by the human body except
A. the skin as a physical barrier to pathogens.
B. mucus produced in the nasal and oral passages to trap pathogens.
C. wax produced in the ear to trap pathogens.
D. T-cells target specific pathogens.
Answer:
The correct is the answer is option D.
Explanation:
Non-specific defense response is the immune system that provides defense against more than one type of antigen or pathogen. The non-specific defense provides responses include physical barriers, protein defenses, cellular defenses, inflammation, and fever. Mucus in respiratory tracts and nose traps microbes and pathogens from invading the body.
Wax also captured foreign bodies and other pathogens from entering our ears. Non-specific defenses are surface coverage defenses.
T-cells are the specific white cells that target specific antigens or pathogens that are a specific defense provided by the specific immune system.
Thus, the correct answer is option D.
How many more phases occur during meiosis than during mitosis
Answer:
The correct answer would be 4 phases.
Mitosis is a equational division which results in the formation of two daughter cells with equal number of chromosomes as there were in parent cell. It contains four phases prophase, metaphase, anaphase, and telophase. It helps in growth and repair of the cells.
In contrast, meiosis is reductional division which leads to production of four haploid daughter cells from a single diploid parent cell. It usually takes place during the formation of gametes. It takes place in two divisions namely meiosis I and meiosis II.
Meiosis I contains four phases:
prophase Imetaphase Ianaphase Itelophase IMeiosis II also contains four phases:

Human activity on land can have a profound influence on marine ecosystems. True/False
Answer: The given statement is True.
Human activities on land can have a profound influence on marine ecosystems. These include both direct as well as indirect activities by humans, which influence marine ecosystems.
For instance, direct human activities like use of fertilizers in agriculture can have a profound influence on the marine ecosystem. Chemical fertilizers provide extra nutrients to the plants, increasing the fertility of the soil and thereby promote the growth of plants.
These fertilizers are harmful to the aquatic lives. They travel to the marine ecosystem via water run off from the agricultural land. Excess fertilizers cause the formation of algal blooms, which are very toxic. They lead to the lack of oxygen in the water, which results in the loss of aquatic lives.
