can someone please answer these two questions correctly? thank you so much!! ((:
Explanation:
1) 72 of their chromosomes would be somatic and only 2 would be gametes. the number is always two as (normally) an organism will have either 2 X chromosomes (female) or an X and Y chromosome (male).
2) without genetic diversity, an entire species of an organism can go extinct from the same thing as none of them would have mutated any defenses and pass them off to their offspring.
hope this helps :)
Raspberries can reproduce by means of runners, which are stems that grow horizontally above the ground. At the region of the runner that touches the ground, a new plant develops. The new plant is genetically identical to the parent because
Answer:
Explanation:
This is because the new cell is produced asexually. Therefore the mutated cells are similar to the parent.
Asexual reproduction refers to the process where a parent plants reproduce or replicate new plants by itself and the new plants carries the same set of chromosomal numbers thereby been genetically identical to the parent.
These types of cells are found in the reproductive organs and are called
[ germ or somatic ] cells.

A cross of a red cow (RR) with a white bull (WW) produces all roan offspring (RW). This type of inheritance is known as:
sex-linked
complete dominance
codominance
incomplete dominance
Answer:
Codominance
Explanation:
Both parents carry a dominant trait, so the offspring will have a coat of main colour, and also some hairs of another colour.

Select the homologous structures.
a. human arm
b. whale's flipper
c. bird's wing
d. cat's leg
Answer:
Flipper of a whale and bird's wing are homologous structures.
For more better explanation see below.
Explanation:
Flipper of Whale is homologus to the wing of a bird. Homologous organs - The structure which are similar in their morphology, anatomy, genetics and embryology, but dissimilar in their functions.
Flipper of whale and wing of bird has similar morphology and anatomy, but differ in their functions according to their species as well as the habitat where they live in.
A dolphin’s flipper, bird’s wing, cat’s leg, and the human arm are considered homologous structures. Whereas human beings have bones such as the humerus, ulna, radius, wrist bones, and fingers, these features appear as similar bones in form in the other animals. Bats, whales, and many other animals have very similar homologous structures, demonstrating that these creatures all had a common ancestor.

why are metals useful and what are some of their uses?
Answer:
Why are metals useful:
Metals are very useful materials. Metals have many properties, such as strength, toughness, and stiffness. When heated, metals can be shaped into anything from a tiny paperclip to a huge aircraft. They are also good conductors of electricity and heat, which makes them useful for electrics and cooking pans.
What are some of their uses:
As metals are good conductors of electricity, they are used to making wires and parts for equipment and gadgets that function on electrical current.

A neurone is a type of specialised animal cell.
(a) (i) Neurones develop from unspecialised cells.
State the name of these unspecialised cells.
Answer:
Stem cells
Explanation:
Stem cells are immature or unspecialized cells
Neurons develop from unspecialized cells and unspecialized cells are stem cells.
What are the functions of stem cells?
Embryonic stem cells are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage pre-implantation embryo. Human embryos reach the blastocyst stage 4–5 days post fertilization.
Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells.
The cells of the bone marrow produce all of your healthy blood cells, including red blood cells, white blood cells, and platelets.

During meiosis I, how could you have arranged the chromosomes in a different way? How do the differences affect the end result of meiosis??
Explanation:
Meiosis is the formation of reproductive cells, like the egg in the fallopian tube; if not fertilized by sperm, it is expelled by the menstrual cycle.
Some conditions during fertilization can be disrupted by an egg attaching to the fallopian tube instead of the uterus causing an ectopic pregnancy. Arranging chromosomes in a different way causes congenital defects like color blindness, crohn's disease down's syndrome, etc.
Which electromagnetic wave can butterflies,
hedgehogs, and many other animals see?
A. Infrared light
B. Ultraviolet light
C. Microwaves
D. Radio waves
The electromagnetic wave that butterflies, hedgehogs, and many other animals can see is the ultraviolet light that is in Option B, as the ultraviolet light gives these animals a different perspective to visualize.
What role does UV light play in animals?Many animals can see the UV lights, and this is important as the flowers and fruits emit ultraviolet patterns that are invisible to humans but are seen by pollinators such as butterflies and help them find foods.
Hence, the electromagnetic wave that butterflies, hedgehogs, and many other animals can see is the ultraviolet light that is in Option B, as the ultraviolet light gives these animals a different perspective to visualize.

Neutral mutations can have a significant effect on the organism try or false
Answer:
False
Explanation:
Neutral mutations are changes in DNA sequence that are neither beneficial nor detrimental to the ability of an organism to survive and reproduce. In population genetics, mutations in which natural selection does not affect the spread of the mutation in a species are termed neutral mutations.
How are flagella in unicellular organisms like legs in humans??
Cilia and flagella are more closely related, as they are both like hairy extensions from the cell membranes. However Cilia (singular: cilium) are much shorter and are arranged in multiple groups, working together in coordinated manner to create movement along the cell membrane (kind of like the legs of a centipede).

Describe three ways in which the atmosphere interacts with the geosphere.
Answer:
The atmosphere provides the geosphere with heat and energy needed for rock breakdown and erosion. The geosphere, in turn, reflects the sun's energy back into the atmosphere. The biosphere receives gases, heat, and sunlight (energy) from the atmosphere.
