Fluid-filled space between two peritoneums that lubricates mobile organs

What is the mesentery? Where is it found? Single layer of muscle in the chest supporting the lungs Double layer of peritoneum in the abdomen attaching to intestines Triple layer of fat in the legs providing insulation Quadruple layer of skin in the arms protecting muscles

Double layer of peritoneum in the abdomen attaching to intestines

What are the 4 basic layers of the GI tract? Endocardium, myocardium, epicardium, pericardium Cortex, medulla, pelvis, calyx Epidermis, dermis, hypodermis, fascia Mucosal, submucosal, muscularis, serosa

Mucosal, submucosal, muscularis, serosa

What is the significance of lichen in relation to mycorrhizae and coenocytic structures in fungi? Lichen is a type of coenocytic structure. Lichen integrates with mycorrhizae, considering coenocytic factors. Lichen is unrelated to mycorrhizae and coenocytic structures. Lichen competes with mycorrhizae for resources.

Lichen integrates with mycorrhizae, considering coenocytic factors.

How do animals differ from fungi in terms of nutrient acquisition? Animals photosynthesize, unlike fungi. Animals absorb nutrients directly like fungi. Animals use external digestion like fungi. Animals ingest food before digesting it, unlike fungi.

Animals ingest food before digesting it, unlike fungi.

What is the primary difference between diploblasts and triploblasts? Diploblasts have one germ layer; triploblasts have three. Diploblasts have two germ layers; triploblasts have three. Diploblasts have three germ layers; triploblasts have two. Diploblasts have no germ layers; triploblasts have two.

Diploblasts have two germ layers; triploblasts have three.

What is the definition of radial and bilateral symmetry in animals? Radial symmetry: one plane; Bilateral symmetry: multiple planes Radial symmetry: multiple planes; Bilateral symmetry: one plane Radial symmetry: no symmetry; Bilateral symmetry: one plane Radial symmetry: one plane; Bilateral symmetry: no symmetry

Radial symmetry: multiple planes; Bilateral symmetry: one plane

What defines coelomates in the animal kingdom? Bilaterians without a coelom Bilaterians with no mesoderm Bilaterians with a partially lined coelom Bilaterians with a coelom completely lined in the mesoderm

Bilaterians with a coelom completely lined in the mesoderm

What specialized sensory organs can animals have, and what stimuli do they detect?

A cell containing two copies of each chromosome

What is a haploid cell, and how many sets of chromosomes does it contain? A cell that contains two sets of chromosomes A cell that contains four sets of chromosomes A cell that contains a single set of chromosomes A cell that contains three sets of chromosomes

A cell that contains a single set of chromosomes

What are sister chromatids, and how are they connected during cell division? Sister chromatids are joined at the centromere Sister chromatids are joined at the spindle Sister chromatids are joined at the kinetochore Sister chromatids are joined at the telomere

Sister chromatids are joined at the centromere

What is synapsis, and what occurs during this process in meiosis? Chromosomes align at the cell equator Homologous chromosomes pair up and embrace Chromosomes split into chromatids Chromosomes condense and become visible
