Answer:
Volume of rectangular prism = 81 feet³
Explanation:
Volume of rectangular prism is same as volume of cuboid
Length = 9 ft
Width = 4 ft
Height = 2 ft = ft
Volume of rectangular prism = Length × Width × Height
= 9 × 4 ×
= 36 ×
=
= 81 feet³
Answer:
Nucleolus
Explanation:
The nucleolus is a compact structure present in the nucleus of fungal cells and all other eukaryotic cells. The nucleolus is not enclosed by a membrane. Nucleolar organizer present in the nucleolus contains the instructions for the synthesis of ribosomal RNAs.
Ribosomal proteins are synthesized in the cytoplasm. The ribosomal proteins are transported from the cytoplasm into the nucleolus. Assembly of ribosomal proteins and ribosomal RNAs to make ribosomal subunits occur inside the nucleolus which then enters cytoplasm to carry out protein synthesis.
Answer:
C, D, E, F.
Explanation:
Fungi are belongs to multicellular eukaryotic organisms. Fungi are heterotrophs in nature they can not make their own food, and they are playing very important role in nutrient cycle in an ecosystem. They can reproduce from both method sexually and asexually. They are also symbiotic associated with plants and bacteria.
Some statements describe about the body structures or functions of fungi are:
C) Some fungi secrete digestive enzymes into the environment and then absorb the digested nutrients.
D) Mycelia are made up of small-diameter hyphae that form an interwoven mass, providing more surface area for nutrient absorption.
E) Some fungi can grow as either filamentous or single-celled forms.
F) All fungi are heterotrophs; some species live as decomposers and others as symbionts.
Index fossils (also known as guide
fossils, indicator fossils or zone
fossils) are fossils used to define
and identify geologic periods (or
faunal stages).
Answer:
<em>The correct option is C) crossing over and independent assortment</em>
Explanation:
Crossing over and independent assortment can be described as the two essential phenomena of meiosis which brings genetic variations. During crossing over, the exchange of DNA segments between homologous chromosomes takes place. Independent assortment allows the chromosomes to assort independently into gametes hence bringing about the different genetic combinations. Hence, the correct option is C.
Other options, like option A, is false because chromosome inactivation will result in an abnormality.
