Explanation:
Algae are a group of living organisms classified under the kingdom Protista. They exhibit unique characteristics such as mode of reproduction, type of pigment, food reserve material, locomotive ability etc.
A british scientist (botanist) named Felix Eugen Fritsch in 1935 classified algae into 11 different classes based on some of these characteristics. The classes of algae are as follows:
1. Chlorophyceae (green algae)
2. Xanthophyceae (yellow green algae)
3. Chrysophyceae
4. Bacillariophyceae (diatoms)
5. Cryptophyceae
6. Dinophyceae
7. Chloromonadineae
8. Euglenineae
9. Phaeophyceae (brown algae)
10. Rhodophyceae (red algae)
11. Cyanophyceae/Myxophyceae (blue green algae)
Insects: Please choose the correct answer from the following choices, and then select the submit answer button. typically have a younger flying life stage and an older aquatic life stage after metamorphosis. generally give birth to live young. typically mate and produce young during their larval stage. have a respiratory system with spiracles connecting to tracheae.
Answer:
The correct option is ( have a respiratory system with spiracles connecting to tracheae).
Explanation:
The class INSECTA are under the phylum arthropoda which is the largest phylum in the animal kingdom. The insects are mainly land animals, they are widespread and adapted to all types of environment. They are also the only invertebrates that can fly. Examples of insects include: ants, butterflies, beetles, aphids and grasshoppers.
An insect has a well-defined head, thorax and an abdomen. The head had six segments and bears a pair of jointed antennae, compound eyes, simple eyes and mouthparts. The thorax had three segments, each bearing a pair of jointed walking legs. The abdomen has eleven segments and may have sensory and reproductive structures.
An insect carries out gaseous exchange by means of a network of open air tubes or TRACHEAE inside it's body. These tubes have openings called SPIRACLES to the exterior. Therefore the insects have an respiratory system with spiracles connecting to tracheae.
Each of the following will result in complement activation EXCEPT Group of answer choices TLR binding to PAMP on the microbe. recognition of lipid-carbohydrate molecules on the surface of the microbe. lectin binding to mannose on the surface of the microbe. Antibody binding to antigen. All of these will result in activation of complement.
Answer:
TLR binding to PAMP on the microbe
Explanation:
The complement system is a group of proteins in the blood that enhance immune responses by complementing the ability of antibodies and phagocytic cells to mediate effector responses (e.g., lysis, activation of inflammation, opsonization, solubilization of immune complexes, etc). Complement can be activated through the recognition of microbes by soluble pattern-recognition molecules (i.e., lectin pathway) or antibodies (i.e., classical pathway). The classical pathway requires the formation of antigen-antibody complexes for its activation (it is a specific immune response). On the other hand, Toll-like Receptors (TLRs) are molecular receptors that recognize viral and bacterial products (i.e., pathogen-associated molecular patterns or PAMPs), which is a key defense mechanism from the innate immune system response.

The nuclei (the structure inside a cell that contains DNA) of the cheek cells have been stained using a special dye so that they appear purple. What shape are they
Answer: Oval.
Explanation:
The nucleus of a cell is a membranous structure normally found in the center of eukaryotic cells and is where most of the cellular genetic material is found, organized in DNA molecules (deoxyribonucleic acid) associated with proteins such as histones, which make up the chromosomes.
The function of the nucleus is to maintain the integrity of the genes in the DNA and to regulate gene expression to control cellular activities. It then controls when DNA is transcribed into RNA (ribonucleic acid) and when it is exported to the cytoplasm to be translated into proteins.
The nucleus is composed of a nuclear envelope consisting of a double membrane that surrounds it, as well as pores that allow the passage of RNA for the regulation of gene expression.
The cells of the inner cheek are classified as non-keratinized stratified squamous epithelium. An epithelium is a tissue made up of joined cells that line the outer surface of the body and inner organs. Squamous cells are flat, scale-like, whereas stratified cells are arranged in multiple layers. Non-keratinized means that the cells constitute soft tissue found in the moist parts of our body, such as the mouth, stomach, among others. In a normal healthy cell, the nucleus is uniformly stained, oval in shape and smaller in relation to the cytoplasm.

Answer:
The correct answer is D.
Explanation:
The plants are grouped formally into 12 phyla (phylum plural) and are collected in four groupings. These four groupings are based on the history of the evolution of important plant characteristics:
Nonvascular plants evolved earliest. They are distinct from the algae because they preserve the embryo inside of the reproductive structure after fertilization. There is no vascular tissue, xylem, and phloem for these plants to convey nutrients, water, and food. For example, moose, liverwort, and hornworts. These plants do not grow very high without vascular tissue.Vascular seedless plants have evolved into non-vascular tissue but no seeds. The fern, fern, club moss, and horsetails are examples. These plants could grow larger with vascular tissue.Gymnosperms have evolved into seeds but have no blooms. For example, redwood, fir, and cypress trees. Gymnosperms. Gymnos in Greek means "naked"; the gymnosperm seeds are bare, not floral.Flowers or angiosperms have developed into vascular tissue, seeds, and flowers. Angiosperm for example includes magnolia, roses, tulips, and tomatoes.Answer:

What are the methods of waste disposal ? Write in briefly.
Answer:
Methods of waste disposal are :-
Biogas plant: - Biodegradable material is used to produce biogas and manure.
Sewage treatment plant: The drain water is treated at plants before adding it to river.
Land filings: - The waste are buried in low-lying areas and compacted with bulldozers.
Composting: - Organic waste are filled in compost pit to make compost for plants.
Recycle: - This means that you collect plastic, paper, glass and metal items and recycle these materials to make required things instead of synthesizing or extracting fresh plastic, paper, glass or metal. In order to recycle, we first need to segregate our wastes so that the material that can be recycled is not dumped along with other wastes.
Reuse: - This is actually even better than recycling because the process of recycling uses some energy. In the ‘reuse’ strategy, you simply use things again and again. Instead of throwing away used envelopes, you can reverse it and use it again. The plastic bottles in which you buy various food-items like jam or pickle can be used for storing things in the kitchen.
Refuse: -This means to say No to things people offer you that you do not need. Refuse to buy products that can harm you and the environment, say No to single-use plastic carry bags.
Repurpose - This means when a product can no more be used for the original purpose, think carefully and use it for some other useful purpose. For example, cracked crockery, or cups with broken handles can be used to grow small plants and as feeding vessels for birds.
why some fruits have 1 seed and some gruits have many seeds
Answer:
Number of seeds in a fruit depends on the number of ovules in an ovary before fertilizations. The fruits which have more seeds in them have more number ovules in the ovary of flowers such as watermelon and those with single seed have only single ovule in the ovary of flowers like mango
Answer:
Number of seeds in a fruit depends on the number of ovules in an ovary before fertilisation. The fruits which have more seeds in them have more number ovules in the ovary of flowers such as watermelon and those with single seed have only single ovule in the ovary of flowers like mango.

Write a supported hypothesis of how the body would react if the peripheral nervous system was shut down while the central nervous system continues to function.
Explanation:
The real magnitude of this challenge can perhaps be best judged by considering the structural and functional complexity of the human brain and the bewildering complexity of human behavior. The human brain is thought to be composed of about a hundred billion (1011) nerve cells and about 10 to 50 times that number of supporting elements or glial cells. Some nerve cells have relatively few connections with other neurons or with such effector organs as muscles or glands, but the great majority receive connections from thousands of other cells and may themselves connect with several hundred other neurons. This means that at a fairly conservative estimate the total number of functional connections (known as synapses) within the human brain is on the order of a hundred trillion (1014). But what is most important is that these connections are not random or indiscriminate:
They constitute the essential "wiring" of the nervous system on which the extraordinarily precise functioning of the brain depends. We owe to the great neuroanatomists of the last century, and especially to Ramón y Cajal, the brilliant insight that cells with basically similar properties are able to produce very different actions because they are connected to each other and to the sensory receptors and effector organs of the body in different ways. One major objective of modern neuroscience is therefore to unravel the patterns of connections within the nervous system—in a word, to map the brain.

How would the introduction of a predator species affect the stability of an
ecosystem?
A. The stability would not change because the new predator would
simply replace the native predator.
B. The stability of the ecosystem would increase as a result of the
introduction of a new predator species.
C. The new predator would be unable to hunt effectively for native
prey, so the stability would not change.
D. The native prey might not be able to protect itself against the new
predator, so the prey population would probably decline rapidly.

During cellular respiration, the first CO2 is generated during _____ and the remaining carbons are given off as CO2 during _____.
Answer:
Glycolysis and Krebs cycle.
Explanation:
During cellular respiration, the first carbondioxide gas is generated during glycolysis while the remaining carbons are given off as carbondioxide during Krebs cycle. During the process of glycolysis in cellular respiration, glucose is oxidized forming carbondioxide and water whereas during the Krebs cycle, the two carbon atoms of acetyl-CoA are released and each turns into a carbondioxide molecule.

Why do biologists classify
Answer:
Biologists classify organisms because:
Classification allows us to understand diversity better. It helps in the identification of living organisms as well as in understanding the diversity of living organisms. Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences. It enables us to understand how complex organisms develop from simpler organisms. They are grouped under different categories to understand and study the features, similarities and differences between different living organisms. It is essential to understand the inter-relationships among the different groups of organisms. Classification forms a base for the development of other biological sciences.Mr. Lim wants to start a sustainable oil palm plantation.
