Answer:
Explanation:
Duplicated centrioles are responsible for moving chromosomes during mitosis.
They are involved in the formation and organization of spindle during cell division (mitotic phase) and also in the process of cytokinesis.
It is composed of nine triplets of microtubules that are the proteins of cytoskeleton.
Spindle fibres contain multiple proteins that help in the binding with centromere during cell cycle.
They originate from the poles of the cell by the organelle called centriole, and attached to the kinetochore of the chromatid.
Many spindle fibres are just connected between two poles, as they are not attached to the chromatids.
These fibres orient the chromosomes into pairs, to the metaphase plate into a line during metaphase.
During anaphase they are shortened, which pulls the chromosomes to the opposite poles separated from the pairs.
At the end in telophase, where nuclear membrane becomes visible it disappears.
In this way the spindle fibers help in the separation of chromosomes into two new daughter cells. This process is also known as the distribution of heredity or genetic information between new cells.

The thallus of a mold consists of long, branched, threadlike filaments of cells called _________ that form a tangled mass called a
Answer:
Hyphae; mycelium.
Explanation:
Fungi can be defined as living microorganisms that are eukaryotic in nature and are able to reproduce using both means of reproduction i.e both asexually and sexually. Also, fungi do not have chlorophyll but are of great importance to the human world both scientifically and practically.
A thallus can be defined as the vegetative or bodily structure of fungi. Thus, the various forms of fungi are;
I. Yeast.
II. Mushroom.
III. Mold.
A mold is typically multicellular (has more than one cell) and filamentous in nature. The thallus of a mold consists of long, branched, threadlike filaments of cells called hyphae that form a tangled mass called a mycelium.
The thallus of a mold consists of long, branched, threadlike filaments of cells called Hyphae that form a tangled mass called a mycelium.
What are hyphae and mycelium in fungi?Hyphae are the tubular projections of multicellular fungi that form a filamentous network. Fungal hyphae release digestive enzymes in order to absorb nutrients from food sources.
mycelium, the mass of branched, tubular filaments of fungi. The mycelium makes up the thallus, or undifferentiated body, of a typical fungus.
Thus, hyphae and mycelium is the correct answer.

The graph below represents the effect of enzyme concentration on the reaction rate.
Based on this graph, what can you conclude about the relationship between enzyme concentration and the rate of starch chemical reaction? (ASK 1a1)(DOK1)
Question 4 options:
a. The reaction rate decreases as the enzyme concentration increases
b. The reaction rate increases as the enzyme concentration decreases
c. The reaction rate increases as the enzyme concentration increases
d. The reaction rate is indirectly proportional to the enzyme concentration
Answer:
C
Explanation:
Increasing enzyme concentration will speed up the rate of a reaction, as long as there is substrate available to bind to.
Rate of reaction is directly proportional to the enzyme and substrate concentration. Therefore, option (C) is correct.
What is enzyme- substrate complex ?
An enzyme-substrate complex is what happens when a substrate attaches to an enzyme's active site during a chemical process. Aspects including temperature, pH, co-factors, activators, and inhibitors can affect an enzyme's activity.
A substrate is placed into the active site of the enzyme, or the location where weak bonds can form between two molecules. An enzyme substrate complex is created, and the enzyme's pressures on the substrate cause it to react and turn into the reaction's intended product.
Therefore, option (C) is the correct option as long as there's enough substrate for enzyme to bind and convert to product.

Chromatids are distributed to the 2 daughter nuclei Group of answer choices
M
G2
S
G1
Answer:
M
Explanation:
Mitosis is a type of cell division that involves the production of two daughter cells that are genetically identical to one another. Mitosis encompasses two stages namely: Interphase and Mitotic phase. The interphase which further consists of G1, S, and G2 phases, is a preparatory phase for the cell to grow and replicate its DNA.
However, the separation of the sister chromatids (replicated chromosomes) into two daughter nuclei occurs in the Mitotic or M phase. Note that the M phase comprises of stages that includes: prophase, metaphase, anaphase and telophase.

M phase

Three that live in the savanna are lions, giraffes, and elephants. Choose two of these animals. For each one, describe an adaptation that has enabled it to survive in the savanna. Then tell which which animals in the population would be more likely to survive if a dry season was unusually long.
Giraffes and Elephants: Giraffes have adapted a long neck over time letting them eat and access food allowing them to survive. If a dry season was unusually long they would succeed fine because they are able to eat and drink from the trees. Elephants have survived with similar tactics of eating higher up, they have rough skin allowing them to outlast the heat, and only need water after long periods of time.
