A) 04
B) 05
C) O9
D) 10
Answer:
10
Explanation:
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.
What is dichotomous key?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.

pls hurry In which parts of the cell cycle would chromosomes be paired up? Check all that apply. interphase metaphase I anaphase II telophase II metaphase II telophase I
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.

How are the endoplasmic reticulum and Golgi apparatus
similar?
Both contain their own kind of DNA.
O Both are made up of membranes consisting of a lipid bilayer.
O Both are involved in producing chemical energy for the cell.
O Both are found only in plant cells and not in animal cells.
Answer:
Both are made up of membranes consisting of a lipid bilayer.
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life.
Generally, cells have the ability to independently replicate themselves. These cells can be compared to the kind of structures found in a business or factory, where you have different workers performing different functions.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.
Golgi apparatus is like a packaging unit because it prepares the protein for export by chemically tagging them.
Also, the endoplasmic reticulum is like an assembly line because it is where the ribosomes perform their tasks.
Hence, the endoplasmic reticulum and Golgi apparatus are similar because both are made up of membranes consisting of a lipid bilayer.

Explain how brassinosteroids are synthesised, perceived and promote plant growth and development. Please give named examples and critical analysis to support your answer
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.

Which of the following best compares the functions of the ovaries and the uterus? (1 point)
Embryos are formed in the ovaries and zygotes are produced in the uterus during fertilization.
Zygotes are fertilized in the ovaries and develop into fetuses in the uterus.
Eggs are produced in the ovaries and zygotes implant in the uterus.
Eggs are fertilized in the ovaries and mature in the uterus.
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.

Which conclusion is best supported by the information?
A. The protist is an animal-like flagellate because it has
a flagellum.
B. The protist is a plant-like dinoflagellate because it
produces oxygen.
C. The protist is a plant-like dinoflagellate because it was
found in salt water.
D. The protist is an animal-like flagellate because it has
a nucleus.
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

your best friend has five children and they are all boys. They are expecting their 6th child. What would be the probability for their 6th child to be a girl? Why
Answer:
50% or 1/2
Explanation:
The probability of their 6th child being a girl would be 50% or 1/2.
During meiosis, the female produces X eggs while the male produces X and Y sperms. A random fusion of gametes then occurs during fertilization.
XX x XY
XX (female) XY (male) XX (female) XY (male)
XX - 1/2 or 50%
XY - 1/2 or 50%
Hence, the probability of producing a girl is 1/2 or 50% irrespective of the number of kids a couple might have produced already.
