Answer:
false
Explanation:
thin skin actually has more extensive dermal layer - this make thin skin easier to stitch while thick skin is found on fingertips & soles of the feet
Answer:
C. two tetramers of histone proteins
Explanation:
The nucleosome core particle is responsible for packaging DNA in the chromosomes. The protein components that make up the nucleosome core are two tetramers of histone proteins. One of which is composed of two units each of histones H2A and H2B, while the other one is composed of two units each of histones H3 and H4. Thus making up the entire protein component of the nucleosome core.
Answer:
<u>The process of photosynthesis occurs in the chloroplast</u>. Photosynthesis can be described as a process in which plants convert water and carbon dioxide into glucose and oxygen. Oxygen is the by-product of the reaction. The energy for this reaction is taken by the chloroplast by trapping light energy of the Sun.
The reaction for photosynthesis can be written as:
6CO2 + 6H2O → C6H12O6 + 6O2
<u>The process of cellular respiration takes place in the mitochondria.</u> Respiration can be described as a process in which glucose and oxygen get converted into carbon dioxide and water. Energy is released by this process which is used for many cellular activities. Hence, mitochondria is known as the powerhouse of a cell.
The reaction of cellular respiration can be summed up as:
C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP
Both, these processes provide energy for the working of cells.
Answer:
(i) An allele is a variant of a gene, can either be short or tall.
Dominant = the tall allele that "trumps" the short allele. if a dominant and recessive allele is present (heterozygous) then the dominant phenotype will be shown.
(ii) David's eyes are Brown
(iii) Sarah's eyes are blue
(iv) David - B, b
Sarah - b, b
(v) Possible genotypes include Bb and bb. These give the phenotypes of brown eyes or blue eyes.
(vi) The chance for blue eyes is 50% (or 1:1 ratio)
Answer:
Explanation:
No, they cannot survive without plants because carnivore eats the animals which is normally a herbivore and the herbivores eat plant.The animals which lion/wolf/tiger etc eats are mostly herbivores so herbivores would die if plants are not available and lion would not get food .
Lion like all other animals requires Oxygen for survival .The present stock of Oxygen would not lost long in absence of plants.Therefore plants are a must for survival of even the carnivores.
