Answer:

ecosystem

Explanation:

An ecosystem refers to the interaction/relationship between the biotic parts of a habitat with one another and also the abiotic parts. The biotic parts refers to organisms that possess life in them e.g plants, animals, microbes etc while the abiotic parts refers to the inanimate things e.g rocks, sea, land, soil etc.

Therefore, according to this question, an ecologist looking at communities of different species interacting with each other and the abiotic factors of their environment is studying ECOSYSTEM.

A cell if its cytoplasm contains 97% water and 3% solute and it is placed into a container that has a solution of 92% water and 8% solute - cell will lose water and shrink.

A hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic

Thus, A cell if its cytoplasm contains 97% water and 3% solute and it is placed into a container that has a solution of 92% water and 8% solute - cell will lose water and shrink.

Explanation:

Woolly mammoths developed thick fur and large ears to survive in cold climates through natural selection.

The cold climate of the Pleistocene epoch favored the survival of animals that were well-adapted to cold weather. Woolly mammoths had thick coats of fur that helped to keep them warm, and they also had large ears that helped to dissipate heat. Woolly mammoths had a long trunk.

The trunk of the woolly mammoth was used for a variety of purposes, including gathering food, drinking water, and communicating with other mammoths. The trunk was also a valuable tool for helping the mammoth to survive in cold weather.

For example, the mammoth could use its trunk to blow snow away from its food or to reach food that was buried under the snow. Woolly mammoths were social animals. Woolly mammoths lived in herds, which helped them to survive in cold weather. The herds provided protection from predators and helped to keep the mammoths warm.

Answer:

The correct answer is - B. The protist is a plant-like dinoflagellate because it produces oxygen.

Explanation:

Protists are a eukaryotic organism that is not a plant, animal, or fungi but definitely, they all arise from a common ancestor as these single-cell organisms with cell organelles like the nucleus. These shows similarities with all three kingdoms of the eukaryotes. It shows similarities with the animals they move and depend on the particle outside of their body for nutrition and energy.

Plants-like protists are the protist or dinoflagellates that present in freshwater, marine water perform photosynthesis and provide oxygen and glucose in the water for and maintain the oxygen in the water for the organism to breath.

Plant-like protists are essential to the ecosystem. They are the base of the marine food chain, and they produce oxygen through photosynthesis for animals to breathe

easch couplet presents the user with 2 alternatives and exclusive sets of character's.

10 couplets should your key have. If you are building a dichotomous key, and you have 10 species to identify. Hence, option D is correct.

A dichotomous key, a crucial piece of scientific gear, is used to discriminate between diverse species according to their visible traits. Users must choose one of two possibilities to answer a series of questions that make up dichotomous keys.

A dichotomous key in the identification of trees, for instance, would ask whether the tree has leaves or needles. The key then leads the user down one set of questions if the tree has leaves; if the tree has needles, a different set of questions is shown.

The three most prevalent types of dichotomous keys are nested, connected, and branched. Each sentence has the appropriate response written next to it in nested type.

Thus, option D is correct.

Answer:

Brassinosteroids are synthesized from phytosterols and they promote plant growth and development by modulating cellular processes (e.g, cell division, elongation, photomorphogenesis, responses to environmental stimuli, etc).

Explanation:

Brassinosteroids are phytohormones similar to steroid hormones. Phytosterols include sitosterol, campesterol, and stigmasterol, i.e., lipid (cholesterol) molecules that form the cell membranes. These polyhydroxylated steroidal phytohormones play a wide range of cellular roles during plant growth, development and immunity. Examples of brassinosteroid functions include plant development, xylem differentiation, responses to biotic/abiotic stresses, reproduction, etc. For example, campesterol, which is a precursor of brassinosteroid hormones, is an integral membrane component that functions during plant embryogenesis by regulating the permeability of cell membranes and by altering membrane-associated proteins, as well as signal transduction pathways.

Answer:

C. Eggs are produced in the ovaries and zygotes implant in the uterus.

Explanation:

The egg cells are formed in the Ovaries through the process of Ovulation.  The sperm and the egg cell (ovum) fertilize together in the Fallopian Tubes or Oviducts. After fertilization, the zygote formed slowly moves to the uterus, and implants itself into the walls of the uterus. Then, it starts dividing itself into an embryo and later into a complete fetus.

Answer:

metaphase I

Explanation:

The cell cycle encompasses the series of processes that divides a cell into daughter cells. The cell cycle is made of mitosis and meiosis, which are the types of cell divisions. Meiosis occurs in two division steps namely: meiosis I and meiosis II.

The stages in these meiotic process are prophase I and II, metaphase I and II, anaphase I and II, and telophase I and II. Note that, meiosis I involves homologous chromosomes while meiosis II involves sister chromatids. According to this question, Chromosomes pair up in the PROPHASE I stage and remains paired in the metaphase I stage until the separate in the Anaphase stage. Hence, chromosomes will be paired up in the METAPHASE I stage.
