Why are there seasons?

1 answer:

7 0

Answer:The tilt of the Earth's AXIS is the most important reason why seasons occur. We have hot summers and cold winters because of the tilt of the Earth's axis. The tilt of the Earth means the Earth will lean towards the Sun (Summer) or lean away from the Sun (Winter) 6 months later. so it will be c.)

Brums [2.3K]

Answer:

b, d, f, a, e, c

Explanation:

Ca+ binds to troponin -> Troponin removes tropomyosin from G actin -> Myosin binds to actin -> Myosin generates a power stroke -> the sarcomere shortens -> ATP recharges the myosin head

What are the three substances that generally make up paint? describe each part. what are polymers? what is a scanning electron m

pochemuha

The three parts that make up paint are pigments, binders and solvents. Pigments consist generally of organic and non-organic compounds and materials that are added to paint to produce a particular color. Binders are substances that provide support or structure for the pigment and solvents to work. Solvents work to dissolve or disperse these substances into liquid form.
Polymers are a group of atoms that form in repetitious patterns The scanning electron microscope is a microscope that works by shooting beams of electrons at the slide and recording the emissions of the electrons. One advantage is that it has much better magnification than other microscopes

In maize, liguleless (l) is recessive to having ligules (L), and dwarf (d) is recessive to tall (D). These two genes are linked

bearhunter [10]

Answer:

given,

LL║ll and DD║dd,

after crossing over, Ld║Ld × lD║lD

LLdd × llDD

in F1 generation, they will give, LLll, DDdd, LLDD, lldd → LlDd

in eF2 generation, the offsprings will be, LLll × DDdd

LLDD ,LLdd, LLDd, llDD, lldd, llDd, LlDD, Lldd, LlDd

1. yes, these genes are coupling.

2. → phenotypes of parental genes = ligules, liguleless, tall and dwarf

genotypes of parental genes= LLdd, llDD i.e; heterozygous

→ phenotypes of F1 generation = 25% Ligules, 25% tall, 25% ligules-tall, 25% liguleless-dwarf

genotypes of F1 generation = heterozygous ; LlDd that is ligules-tall

3. recombination frequency= no of recombinant / total progeny × 100%

= (1344+1344) / 6156+1344+1344+1156 × 100%

= 2688/ 10000 × 100%

= 26.88 %

that means linkage happened

and the map distance is 26.88 map unit.
