define the term (1)semi-permeable membrane (2) osmosis tell the answer i will mark u as brainlist
Answer:
a)the outermost part of an animal cell that selectively allows things to pass through and come out.
b) the passing of water molecules from higher conc. to lower conc.
Answer:
(a) Semi-permeable membrane:
A semipermeable membrane is a membrane that only allows the movement of solvent molecules but restricts the movement of solute particles across the membrane.
(b) Osmosis:
The process of movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane is called osmosis.
When two nearby concentrations are different, materials will tend to spread out to equalize the concentration. For example, if you put a drop of food colouring in some water it will gradually spread through the whole water.

Which best describes meiosis?
It produces cells that are identical to the original cell.
It is responsible for the replacement of damaged skin cells.
It is responsible for growth of the organism.
It produces male and female sex cells.
Answer:
The best option that describes meiosis is the last one: "It produces male and female sex cells"
Explanation:
Meiosis is the process of making offspring, from the joining of a sperm cell, from a male, and an egg cell, from a female, to the creation of a zygote. In order for life to be created (at least for a human baby), it'll need 46 chromosomes. And so 23 chromosome come from the sperm cell while the other 23 come from the egg cell.
Which of the following is an example of a
homologous trait?
A. the wings of bees and birds
B. the forearm of different animals
C. the DNA of land animals
Answer:
A. the wings of bees and birds
Explanation:
A homologous trait is a trait that is similar morphologically and genetically to one another due to their shared ancestry. This means that the traits are formed from the same ancestors, hence, they are homologous or similar.
According to this question, the wings of bees and birds are homologous because they share the same ancestry.

Answer:
How long the dog runs without stopping
Explanation:
The dependent or responding variable in an experiment is the variable that is dependent on the changes made to the independent variable. It is also the variable that is measured or recorded in an experiment.
In this experiment where a student tests the effect of caffeine on dogs. Three groups of dogs were used for the test and they received water, 10mg caffeine and 50mg caffeine respectively. The different level of caffeine used is tested by recording how long each dog runs without stopping. Hence, how long the dog runs without stopping is the DEPENDENT VARIABLE.

how are hydrogen bond similar to iconic bonds?
Explanation:
Hydrogen bonds are similar to ionic bonds because they both involve the attraction between opposite charges. ... This creates one atom with a negative charge, called an anion, and one atom with a positive charge, called a cation. The attraction between these charges hold the atoms together in an ionic bond.
Hydrogen bonds are inter-molecular bonds. The key difference between hydrogen bond and ionic bond is that ionic bonding exists between permanent anions and cations, whereas hydrogen bonds exist between partial positive and partial negative charges

Determine if this passage is an argument or nonargument: Evolution is central to vertebrate biology because it provides a principle that organizes the diversity we see among living vertebrates. Also it helps to fit extinct forms into the context of living species. Classification, initially a process of attaching names to organisms, has become a method of understanding evolution. --F. Harvey Pough, et al., Vertebrate Life, 7th edition Group of answer choices Nonargument Argument; conclusion: It helps to fit ... the context of living species. Argument; conclusion: Evolution is central to vertebrate biology. Argument; conclusion: Classification ... a method for understanding evolution. Argument; conclusion: It provides a principle ... among living vertebrates.
Answer:
C). Argument; conclusion: Classification,...a method of understanding evolution.
Explanation:
An argument is characterized as 'a series of propositions organized so that the final proposition is a conclusion that is intended to follow logically from the previous propositions.' The given passage exemplifies an argument as it puts forward a claim that can be argued upon if it is true or not and supported through adequate reasoning. The factual evidences are provided to support the validity of the proposition and the conclusion that 'classification initially a process...understanding evolution' is compelled. Thus, option C is the correct answer.

Answer:
D. G1 phaseExplanation:
Interphase is a stage of the cell cycle that occurs between the G1, S, and G2 phases. The first gap phase is also known as the G1 phase. During this phase, the cell expands in size. It duplicates cell organelles and synthesizes molecular components necessary for mitotic division's later stages.
