Answer:
I believe the answer is C
Explanation:
In many plant cells there is a single large central vacuole filled with liquid, pressure of the central vacuole allows plants to support heavy structures such as leaves and flowers.
The organelle that allows plants to support heavy structures such as leaves and flowers is the vacuoles because they are filled with fluid, which provides rigidity. Thus, the correct option for this question is C.
What are the functions of vacuoles in plant cells?The functions of the vacuoles in plant cells are as follows:
It acts as the storage structure in a cell.It can hold food for later use when there is a need for energy from plants.It also collects the complete waste and toxic products of the cell and makes it free from contamination.Vacuoles are membrane-wound cell organelles that can be significantly found in both plant and animal cells. But the difference is that the size of the vacuoles in plant cells is comparatively larger as compared to animal cells.
This cell organelle is typically filled with fluid that constructs the turgor pressure of the cell. The stimulation of pressure allows the plants to assist heavy structures such as leaves and flowers.
Therefore, a vacuole is an organelle that allows plants to support heavy structures such as leaves and flowers. Thus, the correct option for this question is C.

Cytotoxic T cells recognize and kill host cells infected by viruses. They recognize these cells by the foreign antigen displayed on the host cell’s:_________.
A. MHC I molecules
B. MHCII molecules
C. toll like receptors
Answer:
The correct answer is - A. MHC I molecules
Explanation:
Major histocompatibility complexes (MHCs) are presented to different T cells to identify the antigen on the host or infected cell. There are two MHCs - class I and class II. The class I MHC presents to cytotoxic T cells while MHC II to helper T cells.
A cytotoxic T cell only binds to the infected cell displays the foreign antigen such as viruses on the infected cell surface in order to recognize and kill the cells.

The correct chronological sequence of how the endocrine glands are activated during the alarm reaction stage is
Answer:
The correct sequence is: Hypothalamus, Pituitary, Adrenal
Explanation:
The endocrine system comprises of cells, tissues, and organs that discharge hormones as an essential or auxiliary capacity. The endocrine gland is the significant part in this system. The essential capacity of these ductless glands is to discharge their hormones straightforwardly into the encompassing liquid. The interstitial liquid and the veins at that point transport the hormones all through the body. The endocrine system incorporates the pituitary, thyroid, parathyroid, adrenal, and pineal organs

The cladistic principle of monophyly would suggest that: Select one: a. All apes are hominins. b. Outgroups are unhelpful in deciding what species constitute natural groups. c. Birds are reptiles. d. Species boundaries are fuzzy. e. None of the above is correct.
Answer:
c. Birds are reptiles
Explanation:
Phylogeny studies the bonds among the members of a group. The monophyletic groups include the common ancestor and all the descendants. The paraphyletic groups include the ancestor and only a few descendants (not all of them). And the polyphyletic groups include descendants that do not share the same ancestor.
In the exposed example, option C -Birds are reptiles- is the one that describes a monophyletic group. Dinosaurs are reptiles, and birds evolved from them. So, according to the cladistic principle, dinosaurs are the common ancestors of all reptiles, and birds are one of the descendants. The group reptilia include the dinosaurs and all their descendants, and reptilia would not be a monophyletic group unless they include birds among them. As birds evolved from dinosaurs, they are reptiles.

which kind of cells carry out the process of cellular respiration?
All living cells must carry out cellular respiration. It can be aerobic or anaerobic respiration. Prokaryotic cells carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells, while Mitochondria carry out the cellular respiration in eukaryotic cells. They are also called as the 'Power house' of the cell as they produce the energy needed to the cell to function properly.
1. The parts of the flower involved in reproduction are ________ and __________
2. The anthers bear the ___________the microspore mother cells give rise to _______or pollen grains after meiotic cell division.
Answer:
1. Stamen and pistil
2. Pollen, microspore
Explanation:
The flower is the reproductive part of certain plants called ANGIOSPERMS. They make use of their flower for sexual reproduction. The different parts of the flower work together to achieve a common goal, which is to reproduce, however, they do it in various ways. For example, accessory parts like petals attract pollinators. The major parts of the flower that are directly involved in the reproductive act are STAMEN (male) and PISTIL (female).
The stamen which constitutes a structure called ANTHER bears the pollen grains or microspore, which is made when the microspore mother cells undergo meiotic division. Hence, the pollens are released from the anther of a male flower (stamen), into the stigma of the female flower (pistil).

Which organisms replicate cells by mitosis?
Answer:
All organisms, both prokaryotes and eukaryotes, can replicate cells by mitosis.
Explanation:
Mitosis is the process of cell division where, from a progenitor cell, two identical daughter cells are obtained. In the human being this process is carried out by somatic cells.
Cell division by mitosis is carried out by all living beings:
Prokaryotic organisms, unicellular, use it as a means to reproduce. Eukaryotic organisms, most of them pluricellular, use it in the processes of growth, development, repair and regeneration of tissues.All living beings can perform mitosis as a process of cell replication, although with different objectives.

Answer:
stores extra food
is responsible for photosynthesis
supports the plant
makes up the majority of a plant
Explanation:
Ground tissues are one of the three types of plant tissues (others being dermal and vascular). They are composed of cells as follows: parenchyma, collenchyma, and sclerenchyma. These three cells that make up the ground tissues perform different functions in the plant cell.
- Parenchyma functions in photosynthesis and storage of extra food (carbohydrates) in the cell.
- Collenchyma functions in the support of young regions of the plant
- Sclerenchyma, which has the thickest cell wall, functions mainly in the strengthening/support of the plant cell.
Also, among the three tissue types in a plant, ground tissues make up majority of the plant cell.
Mitosis and meiosis differ in the way chromosomes move and in their number of cell divisions A cell replicates, or copies, all its chromosomes before entering either mitosis or meions in mitosis however, each daughter
Call receives an identical complete diploid set of chromosomes
By contrast during Meiosis, what do daughter cells receive?
Moi
Answer: C
Explanation:
During meiosis, each chromosome will divide to give rise two diploid daughter cell, each daughter cell receives haploid set of chromosome.
What is meiosis ?Meiosis is the process where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.
Humans have 46 chromosomes in every cell, where 23 chromosomes came from one of our parents and 23 very similar chromosomes that came from the other parents.
Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibres appear.
Secondly Prometaphase I where Spindle fibres attach to the centromere followed by Metaphase I where The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.
Telophase I where Spindle fibres disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells.
